Question

Evaluate the series

Answer 1

The answer to evaluate the series is:

26

Answer 2

Answer:

$26$.

Step-by-step explanation:

The given series is;

$\sum_{n=1}^{4}(n+4)$.

This series is finite and has few number of terms.

We can rewrite the expanded form to get;

$\sum_{n=1}^{4}(n+4)=(1+4)+(2+4)+(3+4)+(4+4)$.

$\sum_{n=1}^{4}(n+4)=5+6+7+8$.

$\sum_{n=1}^{4}(n+4)=26$.
