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

Answer:

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

Step-by-step explanation:

The geometric series in the form

$a, ar, ar^{2},....$

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

$r = \frac{ar}{a}$

As given the sequence in the question

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

a = 0.1

ar = 0.01

$r = \frac{0.01}{0.1}$

r = 0.1

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