Question

Determine whether each sequence is a geometric sequence. If yes, then state the common ratio.

5, 10, 15, 20,...

Answer 1

Explanation:

it is not a geometric sequence

Answer 2

no

Explanation:

Take the second term and divide it by the first term

10/5 = 2

Take the third term and divide it by the second term

15/10 = 3/2

The ratio is not the same so it is not a geometric sequence
