It is a geometric sequence and common ratio is

#### Explanation:

To find whether a given sequence is geometric sequence or not, we should divide each term by its preceding term to find ratio between them.

If we get the same ratio, it is a geometric sequence.

Here, we are given the sequence as

as

As ratio is same, it is a geometric sequence and common ratio is
