Question

Determine whether the following sequence is geometric. If​ so, find the common ratio.

3​, 6​, 12​, 24​, ...
Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.
A.
The given sequence is geometric. The common ratio r=___ (Simplify your​ answer.)
B.
The given sequence is not geometric.

Answer 1

A

Explanation:

The given sequence is geometric. The common ratio is r=2.

If we divide each term by its previous, we would get:

r=3/6=2

r=12/6=2

r=24/12=2

Thus, r=2.
