Question

Determine 3rd term in the geometric sequence whose first term is -8 and whose common ratio is 6 nter poration. All Rights Reserved

Answer 1

Geometric Sequence is written as

{a, ar, ar², ar³, ... } ...... (1)

where:

• a is the first term, and
• r is the factor between the terms (called the "common ratio")

First term a = -8

common ratio r = 6

From equation (1) third term is   $ar^{2}$

$-8*6^{2} = -288$
