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

Answer:
3.2, 12.8, 51.2,204.8
Step-by-step 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
