Analyze and Graph Number Patterns Practice Test

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)?

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?
