Question

Given the following geometric sequence, find the common ratio: {16, 64, 256, ...}.

Answer 1

Answer:

The common ratio is 4

Step-by-step explanation:

We need to divide a term by the previous term to find the common ratio in a geometric sequence:

64 ÷ 16 = 4

256 ÷ 64 = 4

By doing it twice we can confirm that the common ratio is 4

Answer 2

Given the following geometric sequence, the common ratio would be 4.
