What is the sum of the series *picture attached*
Ksivusya [100]

Answer:

\sum_{n=4}^{18}(n+1)^2=2440

Step-by-step explanation:

Series: \sum_{n=4}^{18} (n+1)^2

Formula :\sum_{k=m}^n=\sum_{k=1}^n-\sum_{k=1}^{m-1}

\Rightarrow \sum_{n=4}^{18}(n+1)^2=\sum_{n=1}^{18}(n+1)^2-\sum_{n=1}^{3}(n+1)^2

\sum_{n=1}^{18}(n+1)^2=2469

\sum_{n=1}^{3}(n+1)^2=29

\Rightarrow \sum_{n=4}^{18}(n+1)^2=2469-29

\Rightarrow \sum_{n=4}^{18}(n+1)^2=2440

So, Option C is true
