Question

Explain how to find the common ratio of a geometric sequence.

Answer 1

hello :
common ratio of a geometric sequence is : r = (an+1)/(an)
for exemple a geometric sequence: 3,6,12,24
r= 24/12 = 12/6= 6/3 = 2

Answer 2

In a geometric sequence, the common ratio can be find dividing the second term by the first term.

Explanation:

In a geometric sequence, the common ratio can be find dividing the second term by the first term.

For instance, a geometric sequence: 2, 4, 8, 16, 32...

Common ratio (r)= 4/2 = 2

r = 2

Hope this will helpful.

Thank you.
