Question

Which expression represents the series

Answer 1

That would be the first choice:

5^0 = 1 , 5^1 = 5, 5^2 = 25 and so on up to 5^4 = 625

Answer 2

The first option is the correct answer.

Explanation:

The given series is :

1 + 5 + 25 + 125 + 625

We get ;

`5^0=1`

`5^1=5`

`5^2=25`

`5^3=125`

`5^4=625`

We can see that the power/exponent is ranging from 0 to 4.

So, the first option is the right answer where 'i' goes from 0 to 4.
