Question

Find the ninth term of the geometric sequence if a1 = 7 and r = 2

Answer 1

The ninth term of the geometric sequence is 1,792.

Explanation:

Answer 2

For the geometric sequence:
a n = a 1 * r^(n-1)
a 1 = 7
r = 2
a 9 = a 1 * r^8 =
= 7 * 2^8 = 7 * 256 = 1,792
Answer:
The ninth term of the geometric sequence is 1,792.
