Answer:
a = 0.25
r = 4
n = 5
Step-by-step explanation:
Given series is,
0.25 + 1 + 4 + 16 + 64
Ratio of 2nd and 1st term = [tex]\frac{1}{0.25}[/tex]
= 4
Ratio of 3rd and 2nd terms = [tex]\frac{4}{1}[/tex]
= 4
There is a common ratio 'r' = 4
First term of the given geometric series 'a₁' = 0.25
n = Number of terms in the series
n = 5
