Question

What are the first four terms of a geometric sequence if its common ratio is 4 and its first term is 3.2?

Answer 1

3.2, 12.8, 51.2,204.8

Explanation:

simply use the common formula of geometric series:

tn= a.r^(n-1)

where, tn= nth term (term whose value you want to obtain)

a= first term

r= common ratio

n= nth value
