Question

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

Answer 1

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.
