Answer 1

a = 0.25

r = 4

n = 5

Explanation:

Given series is,

0.25 + 1 + 4 + 16 + 64

Ratio of 2nd and 1st term =
`(1)/(0.25)`

= 4

Ratio of 3rd and 2nd terms =
`(4)/(1)`

= 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
