Question

Find the fourth term of the

geometric sequence, given the
first term and common ratio.
a=8 and r=4

Answer 1

The fourth term of the geometric sequence is 512.

Explanation:

To find the geometric sequence of the nth term we will use the formula:

An = a×r^(n-1)

As, we have to find the fourth term,

A4 = 8×(4)^4-1

A4 = 8×64

A4 = 512.
