## Steps for Summation

Step 1 :

Observe the sequence with limits.

Step 2 :

Evaluate the limits with respect to the sequence.

## Problems on Summation

1. ### Evaluate: $\sum_{x = 1}^{5}$ (x2 + 2)

Step 1 :

$\sum_{x = 1}^{5}$ (x2 + 2)

Step 2 :

$\sum_{x = 1}^{5}$ (x2 + 2) = (12 + 2) + (22 + 2) + (32 + 2) + (42 + 2) + (52 + 2) = 3 + 6 + 11 + 18 + 27 = 65

$\sum_{x = 1}^{5}$ (x2 + 2) = 65

2. ### Evaluate: $\sum_{x = 0}^{4}$ (x3)

Step 1 :

$\sum_{x = 0}^{4}$ (x3)

Step 2 :

$\sum_{x = 0}^{4}$ (x3) = 13 + 23 + 33 + 43 = 1 + 8 + 27 + 64 = 100

$\sum_{x = 0}^{4}$ (x3) = 100
