Example Questions
Example Question #2 : Patterns And Sequences
What number replaces the circle in the following sequence?
Add 2 to the first number to get the second; each subsequent increment is increased by 2. The pattern:
Add 12 to get the next element:
Example Question #7 : Patterns And Sequences
What number replaces the circle in this sequence?
After the first two elements, each subsequent element is the sum of the previous two (similar to the Fibonacci sequence).
The third and subsequent elements are calculated as follows:
Example Question #1 : Patterns And Sequences
What number replaces the circle in the following sequence?
The sequence consists of the perfect square integer, except that every other element is negated. The sequence goes like this:
The next entry is 
Example Question #9 : Patterns And Sequences
Which of the following could be equal to 
We need to find ways to factor 28 such that the three factors are different, and then find the sum of those factors in each case.
28 can be expressed as the product of three integers four ways:
I) 
II)
III)
IV)
We disregard (I) and (IV) since the factors are not distinct.
We look at (II) and (III):
II: Sum:
III: Sum:
Of the four choices, only 17 is a possible sum; that is the correct choice.
Example Question #1 : Patterns And Sequences
What property of arithmetic is symbolized below?
If 
Associative
Distributive
Transitive
Reflexive
Transitive
The symbols express the idea that two numbers equal to the same number are also equal to each other. This is the transitive property of equality.
Example Question #11 : Patterns And Sequences
What property of arithmetic is symbolized below?
If 
Associative
Inverse
Transitive
Commutative
Transitive
The symbols express the idea that if a number is greater than a second number, which is greater than a third, then the first number is greater than the third. This is the transitive property of inequality.
Example Question #12 : Patterns And Sequences
What is the next number in the series?
The series follows the pattern
Plug in the last number given:
Example Question #13 : Patterns And Sequences
What number comes next in the sequence?
The numbers can be seen as increasing by four per term since:
This means the term after three is four more than three.
The answer is:
Example Question #11 : Patterns And Sequences
Give the next number in the sequence:
Each term of the sequence is found by adding a number to the previous one; the number added is incremented by 2 each time, as seen below:
The next term, which is the missing term, is obtained by adding 12 to 26:
the correct choice.
Example Question #15 : Patterns And Sequences
What is the next number in the following sequence?
Understanding this sequence takes a quick eye, so to speak. Notice this interesting fact. You can rewrite the sequence as follows:
That is a rather simple sequence if you think of it. The best clue to help you see it will likely be the transition between
