Calculating the Sum of 1 to 100

To find the sum of the numbers from 1 to 100, you can use the formula for the sum of an arithmetic series, which is given by:

Sum = (n/2)(first term + last term)

Where: - n = number of terms - first term = 1 - last term = 100

Using this formula, the sum of the numbers from 1 to 100 can be calculated as follows:

Sum = (100/2)(1 + 100) Sum = 50 * 101 Sum = 5050

This means that the sum of the numbers from 1 to 100 is 5050.
