What is the sum of the numbers from 1 to 100?

Given :

The numbers are from 1 to 100.

To do :

We have to find the sum of the numbers from 1 to 100.

Solution :

Sum of n natural numbers is given by $\frac{n(n+1)}{2}$.

Therefore,

Sum of the numbers from 1 to 100 $= \frac{100(100+1)}{2}$

                                                             $= 50 \times 101$

                                                              $= 5050$.

Therefore, the sum of the numbers from 1 to 100 is 5050.
