Sum of Numbers and Pairing Method

The video tutorial explains how to find the sum of numbers from 1 to 100 using a pairing strategy. By adding the first and last numbers, and continuing this pattern, each pair sums to 101. With 50 pairs in total, the sum is calculated as 50 multiplied by 101, resulting in 5050.
