The first term of a geometric sequence is −4300. The common ratio of the sequence is −0.1.

What is the 8th term of the sequence?

The equation we'll use is an=a1rn-1.

an is the quantity of the nth term, a1 is the first term of the sequence, r is the common ratio, and n is the term you are trying to find.

 

Given:

a1=-4300

r=-0.1

n=8

 

Substitute:

an=(-4300)(-0.1)8-1

 

Calculate:

an=0.00043
