What is the sum of the series?
allsm [11]

The sum of given series is 44

<em><u>Solution:</u></em>

Given that we have to find the sum of the series

<em><u>Given series is:</u></em>

\sum_{k=1}^{4}\left(2 k^{2}-4\right)

Substitute k = 1 to k = 4 to find the sum of the series

When k = 1:

\rightarrow 2(1)^2 - 4 = 2 - 4 = -2

When k = 2:

\rightarrow 2(2)^2 - 4 = 2(4) - 4 = 8 - 4 = 4

When k = 3:

\rightarrow 2(3)^2 - 4 = 2(9) - 4 = 18 - 4 = 14

When k = 4:

\rightarrow 2(4)^2 - 4 = 2(16) - 4 = 32 - 4 = 28

<em><u>Therefore, the sum of series is given as:</u></em>

\sum_{k=1}^{4}\left(2 k^{2}-4\right)=-2+4+14+28=44

Thus the sum of series is 44
