Question

Find the common ratio for the following sequence.

0.1, 0.01, 0.001,

Answer 1

The common ratio is 0.10

Explanation:

0.1 x 0.1 = 0.01

0.01 x 0.1 = 0.001

common ratio is the ratio of a term to the previous term.

0.1 is the previous term of 0.01

common ratio = 0.01/0.1 = 0.10

common ratio = 0.001/0.01 = 0.10
