Answer 1

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 = $\frac{1}{0.25}$

                                          = 4

Ratio of 3rd and 2nd terms = $\frac{4}{1}$

                                             = 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
