Question

Find the common ratio for the following sequence. 0.1, 0.01, 0.001, ...

Answer 1

0.1 is the common ratio, you can see them all being multiplied by 0.1, hope this helps!

Answer 2

The common ratio of the sequence. 0.1, 0.01, 0.001, ...... is 0.1 .

Explanation:

The geometric series in the form

`a, ar, ar^(2),....`

Where a is the first term r is the common ratio .

`r = (ar)/(a)`

As given the sequence in the question

0.1, 0.01, 0.001, .......

a = 0.1

ar = 0.01

`r = (0.01)/(0.1)`

r = 0.1

Therefore the common ratio of the sequence. 0.1, 0.01, 0.001, ...... is 0.1 .
