Algebra Nation - Section 7 (Exponential Functions)

In a Geometric Sequence, what does r represent?

• Radical

• Common difference

• Common ratio

What are the next 3 terms in the following geometric sequence:

512, 256, 128, ___, ___, ___, ...

• 1024, 2048, 4096

• 32, 8, 2

• 64, 32, 16

• 92, 66, 38

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

• yes
• no

Find the common ratio: 4, -16, 64, -256, ...

• r = -4
• r = 2
• r = -2
• r = 4

Determine whether the sequence is arithmetic, geometric, or neither.
