Step 1

To Determine: whether the sequence is arithmetic, geometric, or neither. If the sequence is arithmetic, find the common difference, if it is geometric, find the common ratio.

Given: we have the general term of a sequence

Explanation: we have

now we can write down the sequence by putting

so we have

this sequence is G.P because this give same common ratio

Step 2

and so on.hence the common ratio will be
