Two patterns are paired term-by-term to make ordered pairs $(x, y)$ and graphed on the coordinate plane.
Pattern X rule: start at 1 and add 2. Terms: 1, 3, 5, 7, 9.
Pattern Y rule: start at 2 and add 4. Terms: 2, 6, 10, 14, 18.
Which ordered pair represents the 3rd terms of the patterns (with $x$ from Pattern X and $y$ from Pattern Y)?
$(10, 5)$
$(5, 10)$
$(7, 10)$
$(5, 14)$
Explanation
Number patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate terms in a pattern, start with the initial value and repeatedly add the given increment, such as starting at 1 and adding 2 to get 1, 3, 5, 7, 9 or starting at 2 and adding 4 to get 2, 6, 10, 14, 18. Forming ordered pairs involves taking the nth x from Pattern X and y from Y, so the 3rd is (5,10). The graph shows the relationship by plotting these, revealing y grows twice as fast as x. A common misconception is confusing term positions, but the 3rd terms are clearly 5 and 10. Graphs help visualize pattern relationships by highlighting specific paired values. Overall, such graphs allow us to identify and confirm individual ordered pairs accurately.
In a science notebook, Pattern M starts at 5 and follows the rule “add 1.” Pattern N starts at 2 and follows the rule “add 3.”
Generated terms:
- Pattern M: 5, 6, 7, 8
- Pattern N: 2, 5, 8, 11
Ordered pairs are made using corresponding terms as $(M, N)$ and then graphed in the first quadrant.
Which ordered pair represents the patterns at the 2nd term?
The ordered pair is $(6, 5)$.
The ordered pair is $(5, 6)$.
The ordered pair is $(6, 8)$.
The ordered pair is $(7, 5)$.
Explanation
Patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate pattern terms, start with the initial value and repeatedly apply the rule, such as adding 1 to 5 for Pattern M to get 5, 6, 7, 8, and adding 3 to 2 for Pattern N to get 2, 5, 8, 11. Form ordered pairs by matching the nth term of Pattern M with the nth term of Pattern N, like (5,2), (6,5), (7,8), and (8,11). The graph shows the relationship by plotting these points, revealing N catching up to and surpassing M. A common misconception is reversing the order in pairs, but they follow the specified (M,N) format, so the second pair is (6,5). Graphs help visualize how patterns evolve relative to each other over multiple terms. Overall, graphing paired patterns illustrates trends like convergence or divergence, aiding in predicting future relationships.
In art class, Maya makes two bead patterns.
Pattern A rule: start at 2 and add 3 each time. Terms: 2, 5, 8, 11, 14.
Pattern B rule: start at 4 and add 2 each time. Terms: 4, 6, 8, 10, 12.
Pair the 1st terms, 2nd terms, 3rd terms, and so on to make ordered pairs $(A, B)$: (2,4), (5,6), (8,8), (11,10), (14,12).
These ordered pairs can be graphed to compare the patterns. Which relationship between the patterns is shown by the ordered pairs?
Pattern A starts smaller, but after the third pair it becomes greater than Pattern B.
Pattern A is always 2 less than Pattern B.
Pattern B is always 2 more than Pattern A.
Pattern A and Pattern B are equal for every paired term.
Explanation
Number patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate terms in a pattern, start with the initial value and repeatedly add the given increment, such as starting at 2 and adding 3 to get 2, 5, 8, 11, 14 or starting at 4 and adding 2 to get 4, 6, 8, 10, 12. Forming ordered pairs involves matching the nth term of the first pattern with the nth term of the second, like (2,4), (5,6), (8,8), (11,10), (14,12). The graph shows the relationship by plotting these points, revealing how Pattern A starts below Pattern B, meets at (8,8), and then surpasses it. A common misconception is that the pattern with the larger starting value always stays larger, but here Pattern A overtakes Pattern B due to its faster growth rate. Graphs help visualize pattern relationships by showing trends like crossing points or relative growth. Overall, such graphs allow us to predict future behaviors and understand how different addition rules affect long-term comparisons.
A student is comparing two patterns by pairing corresponding terms and graphing the ordered pairs in the first quadrant.
Pattern G starts at 6 and follows the rule “subtract 2.” Pattern H starts at 1 and follows the rule “add 2.”
Generated terms:
- Pattern G: 6, 4, 2, 0
- Pattern H: 1, 3, 5, 7
Ordered pairs are formed as $(G, H)$ using corresponding terms.
Which statement about the ordered pairs is correct?
All the ordered pairs can be graphed in the first quadrant because all x-values and y-values are greater than 0.
The last ordered pair cannot be graphed in the first quadrant because its y-value is 0.
None of the ordered pairs can be graphed in the first quadrant because Pattern G is decreasing.
The last ordered pair cannot be graphed in the first quadrant because its x-value is 0.
Explanation
Patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate pattern terms, start with the initial value and repeatedly apply the rule, such as subtracting 2 from 6 for Pattern G to get 6, 4, 2, 0, and adding 2 to 1 for Pattern H to get 1, 3, 5, 7. Form ordered pairs by matching the nth term of Pattern G with the nth term of Pattern H, like (6,1), (4,3), (2,5), and (0,7). The graph shows the relationship by plotting these points, but the last point (0,7) lies on the y-axis, outside the strict first quadrant. A common misconception is that all positive or zero values fit in the first quadrant, but x must be greater than 0 for interior points. Graphs help visualize how patterns evolve relative to each other over multiple terms. Overall, graphing paired patterns illustrates trends like convergence or divergence, aiding in predicting future relationships.
Two patterns are used to plan supplies for art class.
Pattern A rule: start at 2, then add 4 each time. Terms: 2, 6, 10, 14
Pattern B rule: start at 3, then add 2 each time. Terms: 3, 5, 7, 9
A student wrote these ordered pairs $(A, B)$: (2,3), (6,5), (10,7), (14,9).
Which claim about the ordered pairs is incorrect?
The ordered pair (7,10) is correct for the third terms because 7 and 10 both appear in the patterns.
The ordered pair (6,5) matches the second terms of Pattern A and Pattern B.
The ordered pair (14,9) matches the fourth terms of Pattern A and Pattern B.
The ordered pair (2,3) matches the starting values of Pattern A and Pattern B.
Explanation
The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 2 and adding 4 to get 2, 6, 10, 14, and Pattern B starting at 3 and adding 2 to get 3, 5, 7, 9. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (2,3), (6,5), (10,7), and (14,9), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show Pattern A growing faster, with correct ordering essential for accurate representation. A common misconception is reversing pairs like (7,10) for third terms just because numbers appear, but order must be (10,7) to match (A,B). Graphs of paired patterns help visualize ordering errors. Overall, such graphs reveal growth disparities, aiding in verifying claims about specific terms.
Two patterns are paired term-by-term to make ordered pairs $(x, y)$ and graphed on the coordinate plane.
Pattern X rule: start at 1 and add 2. Terms: 1, 3, 5, 7, 9.
Pattern Y rule: start at 2 and add 4. Terms: 2, 6, 10, 14, 18.
Which ordered pair represents the 3rd terms of the patterns (with $x$ from Pattern X and $y$ from Pattern Y)?
$(10, 5)$
$(5, 10)$
$(5, 14)$
$(7, 10)$
Explanation
Number patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate terms in a pattern, start with the initial value and repeatedly add the given increment, such as starting at 1 and adding 2 to get 1, 3, 5, 7, 9 or starting at 2 and adding 4 to get 2, 6, 10, 14, 18. Forming ordered pairs involves taking the nth x from Pattern X and y from Y, so the 3rd is (5,10). The graph shows the relationship by plotting these, revealing y grows twice as fast as x. A common misconception is confusing term positions, but the 3rd terms are clearly 5 and 10. Graphs help visualize pattern relationships by highlighting specific paired values. Overall, such graphs allow us to identify and confirm individual ordered pairs accurately.
Two patterns are shown in a table and can be graphed as ordered pairs $(A, B)$ to show their relationship.
Pattern A rule: start at 1, then add 3 each time. Terms: 1, 4, 7, 10
Pattern B rule: start at 5, then add 1 each time. Terms: 5, 6, 7, 8
Which ordered pair represents the 2nd terms of the two patterns?
$(7, 6)$
$(4, 6)$
$(6, 4)$
$(1, 6)$
Explanation
The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 1 and adding 3 to get 1, 4, 7, 10, and Pattern B starting at 5 and adding 1 to get 5, 6, 7, 8. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (1,5), (4,6), (7,7), and (10,8), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show Pattern A catching up to Pattern B at (7,7) due to its faster addition rate. A common misconception is mixing terms from different positions, like pairing first A with second B as (1,6), but pairs must correspond by order. Graphs of paired patterns help visualize intersection points. Overall, such graphs reveal how patterns converge, aiding in identifying specific term relationships like the second pair (4,6).
Two patterns are used to make ordered pairs $(A, B)$ and then graphed.
Pattern A rule: start at 4 and add 4. Terms: 4, 8, 12, 16, 20.
Pattern B rule: start at 3 and add 2. Terms: 3, 5, 7, 9, 11.
A student claims the ordered pairs should be: (4,3), (8,5), (12,7), (16,11), (20,9).
Which claim about the student’s work is incorrect?
The ordered pair for the 1st terms should be $(3, 4)$.
The student mixed up the last two $y$-values from Pattern B when making the last two ordered pairs.
The student paired the 4th term of Pattern A with the 5th term of Pattern B.
The ordered pair for the 4th terms should be $(16, 9)$.
Explanation
Number patterns can be compared and graphed by pairing their corresponding terms to visualize relationships. To generate terms in a pattern, start with the initial value and repeatedly add the given increment, such as starting at 4 and adding 4 to get 4, 8, 12, 16, 20 or starting at 3 and adding 2 to get 3, 5, 7, 9, 11. Forming ordered pairs involves matching the nth term correctly, but errors like swapping y-values lead to incorrect pairs like (16,11) instead of (16,9). The graph shows the relationship accurately only if pairs are correct, highlighting mistakes in ordering. A common misconception is that the first pair should reverse the patterns, but (4,3) is correct, not (3,4). Graphs help visualize pattern relationships by exposing inconsistencies in plotted points. Overall, such graphs allow us to verify pairings and correct errors in student work.
A student makes two sticker patterns.
Pattern A rule: start at 4, then add 1 each time. Terms: 4, 5, 6, 7
Pattern B rule: start at 1, then add 3 each time. Terms: 1, 4, 7, 10
The student says the ordered pairs $(A, B)$ are: (4,1), (5,4), (6,7), (7,10).
Which claim about the patterns is incorrect?
The fourth ordered pair should be (10,7) because the last terms are 7 and 10.
The first ordered pair should be (4,1) because 4 and 1 are the starting values.
The second ordered pair should be (5,4) because 5 and 4 are the second terms.
The third ordered pair should be (6,7) because 6 and 7 are the third terms.
Explanation
The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 4 and adding 1 to get 4, 5, 6, 7, and Pattern B starting at 1 and adding 3 to get 1, 4, 7, 10. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (4,1), (5,4), (6,7), and (7,10), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show Pattern B catching up to and surpassing Pattern A due to its faster addition rate. A common misconception is reversing the pair order, like claiming (10,7) for the fourth terms, but it must be (7,10) to match (A,B). Graphs of paired patterns help visualize errors in pairing or ordering. Overall, such graphs reveal growth comparisons, aiding in correcting claims about term positions.
Two students track pages read over several days using two patterns.
Pattern A rule: start at 3, then add 4 each time. Terms: 3, 7, 11, 15
Pattern B rule: start at 2, then add 5 each time. Terms: 2, 7, 12, 17
Pair the terms in order to make ordered pairs $(A, B)$.
Which ordered pair represents the 3rd terms of the two patterns?
$(7, 12)$
$(12, 11)$
$(15, 17)$
$(11, 12)$
Explanation
The core skill here is understanding how number patterns can be compared and graphed using ordered pairs to visualize their relationships. To generate pattern terms, follow the given rule, such as starting at a number and adding a constant value each time, like Pattern A starting at 3 and adding 4 to get 3, 7, 11, 15, and Pattern B starting at 2 and adding 5 to get 2, 7, 12, 17. Forming ordered pairs involves pairing corresponding terms from each pattern, such as (3,2), (7,7), (11,12), and (15,17), where the first value is from Pattern A and the second from Pattern B. When graphed, these points show the relationship between the patterns, with the third point (11,12) directly representing the third terms. A common misconception is swapping the order in pairs, like thinking (12,11) is correct, but ordered pairs must follow the (A,B) format. Graphs of paired patterns help visualize how values align at specific positions. Overall, such graphs reveal equality points or differences, aiding in identifying specific term pairs like the correct (11,12).
