CCA Chapter 5 Review

Is the sequence 2, 4, 12, 48,... geometric?

• yes
• no

-21, -16, -11, -6, ...

Is this sequence arithmetic, geometric, or neither?

• arithmetic (common difference d = 5)

• geometric (common ratio r = 5)

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

A sequence can be generated by using a_n = 5a_(n-1)

where a₁ = 3

and n is a whole number greater than 1.

What is the common ratio (r) in the sequence?

• 5

• 3

• neither of these

What kind of sequence is the pattern 15, 17, 20, 24, 29, ...?

• Arithmetic
• Geometric
• Neither

Find the next four terms of the arithmetic sequence 16, 24, 32,...

• 40, 48, 56, 64

• 36, 40, 44, 48

• 35, 40, 45, 50

• 40, 44, 50, 56

Is the sequence geometric? If so, identify the common ratio.

6, 12, 24, 48

• yes, 2

• yes, -2

• yes, 4

• no

A sequence can be generated by using a_n = a_(n-1) +9

where a₁ = 4

and n is a whole number greater than 1.

Which term describes this sequence?

• arithmetic

• geometric

• neither of these
