Question

How do you find the common ratio of `3,6,12,24,...`?

Answer 1

Common ratio is `2`.

Explanation:

In a geometric sequence common ratio is the ratio between a term and its preceding term and is always constant.

Here `6/3=2` for first term and for further terms in the sequence too

`12/6=2` and `24/12=2`.

Hence common ratio is `2`.

Note - In arithmetic sequence, we have common difference.
