What do you call a set of numbers written in a special order by the application of a definite rule?

• Pattern

• Sequence

• Function

• Terms

Which of the following is not an arithmetic sequence?

• 1/2, 1, 3/2, 2

• 11, 14, 17, 20

• 2, 4, 8, 16

• 5, 2, -1, -4

Identify the common difference of the sequence below: -2.3, -1.1, 0.1, 1.3,...

• -1.2

• 1.3

• 1.2

• -1.3

Identify the next three terms of the sequence below:

• -17, -21, -25

• 17, 21, 25

• 18, 22, 26

• -18, -22, -26

• 315

• Arithmetic

• Geometric

Answer explanation

Percentages are almost always Geometric.

What kind of sequence is the pattern 400, 200, 100, 50, 25, ...?

• Arithmetic

• Geometric

• Neither

An ______________sequence is a sequence of numbers in which the difference between any two consecutive terms is a constant. 

• Geometric Sequence

• Arithmetic Sequence

3, 9, 15, 22, ...

Is this sequence arithmetic, geometric, or neither?

• arithmetic (common difference d = 6)

• geometric (common ratio r = 4)

• neither (no common difference OR common ratio) neither (no common difference OR common ratio)

Each individual number in a sequence of numbers is called what?

• Common difference

• Successive term

• Term

• Geometric term
