Example Questions
Example Question #1 : Patterns And Sequences
What is the next number in the series?
39
To pattern uses the formula 
Example Question #1 : Patterns And Sequences
What is the next number in the sequence?
The pattern follows this equation:
Example Question #1 : Patterns And Sequences
What property of arithmetic is symbolized below?
If 
Symmetric
Commutative
Associative
Reflexive
Symmetric
The symbols show that if one number is equal to another, the equality holds no matter the order of the two. This is the symmetric property of equality.
Example Question #161 : Numbers
What property of arithmetic is symbolized below?
Reflexive
Identity
Transitive
Commutative
Reflexive
The symbols express the idea that any number is equal to itself. This is the reflexive property of equality.
Example Question #3 : Patterns And Sequences
What property of arithmetic is symbolized below?
Transitive
Associative
Commutative
Symmetric
Associative
The symbols express the idea that if three numbers are added, the same sum results regardless of which numbers are added first. This is the associative property of addition.
Example Question #1 : 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 #2 : 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 #3 : 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 #2 : 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 
Transitive
Reflexive
Distributive
Associative
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.
