Question

Find the common ratio of the geometric sequence 11, -88, 704,...

Answer 1

-8

Explanation:

Common ratio of a geometric sequence can be obtained by dividing the successive terms as ,

=> S = 11 , -88 , 704

=> r = -88/11

=> r = -8

OR

=> r = 704/-88

=> r = 8/-1

=> r = 8(-1)/(-1)(-1)

=> r = -8

• Hence the common ratio is -8.
