Question

Which expression represents the series pictured?

Answer 1

Hello,
Answer A
$\sum _{i=0} ^4 {5^i}=5^0+5^1+5^2+5^3+5^4=1+5+25+125+625$

Answer 2

Answer:

A. $\sum_{i=0}^{4}5^{i}$

Step-by-step explanation:

We are given the series, $1+5+25+125+625$.

It is required to find expression representing the given series.

As, we have,

$1=5^{0}$

$5=5^{1}$

$25=5^{2}$

$125=5^{3}$

$625=5^{4}$

Thus, it can be seen that the power is ranging from 0 to 4.

Hence, the expression representing the series is, $\sum_{i=0}^{4}5^{i}$

So, option A is correct.
