Select the correct answer. Which expression represents the series? 1+5+25+125+625? creating and solving formulas for geometric series

The given series can be written as

4

∑ (5) ^i

i = 0

We know that the series is

1+5+25+125+625

This is equal to

(5) ^0 + (5) ^1 + (5) ^2 + (5) ^3 + (5) ^4

Thus,

For i from 0 to 4,

We get the general representation.
