To find the common and to see whether the sequence is geometric or not you have to divide n+1 term to n term.

For example 2nd to 1st:
6:2=3
18:6=3

The answer is yes. The sequence is geometric and the common ration is 3. I hope that this is the answer that you were looking for and it has helped you.
