Question

In the formula for the general term of a geometric sequence

Answer 1

The nth term of a geometric sequence can be calculated as:

`t_n=t_1\cdot r^(n-1)`

Where t1 is the initial term and r is the common ratio.

We are given the general term of a geometric sequence:

`t_n=-4\cdot\left((7)/(8)\right)^(n-1)`

When comparing both equations, we know that a1 = -4, r = 7/8

Answer: C 7/8
