Determine if the sequence is geometric. If it is, find the common ratio.

4, 16, 36, 64,

It is not a Geometric Sequence.

Step-by-step explanation:

Step 1: Find if it is a GP. If it is a GP, common ratio would be same for all terms given 4, 16, 36, 64

⇒ a (2) / a (1) = 16/4 = 4

⇒ a (3) / a (2) = 36/16 ≠ 4

⇒ a (4) / (a (3) = 64/16 ≠ 4

Since the common ratio is not the same, it is not a Geometric Sequence.
