## How to Find the Sum of First 50 Even Numbers?

The below workout with step by step calculation shows how to find what is the sum of first 50 even numbers by applying arithmetic progression. It's one of the easiest methods to quickly find the sum of given number series.

step 1 Input Parameters and values:

The number series 2, 4, 6, 8, 10, 12, . . . . , 100.

The first term a = 2

The common difference d = 2

Total number of terms n = 50

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + T_{n})

= 50/2 x (2 + 100)

= (50 x 102)/ 2

= 5100/2

2 + 4 + 6 + 8 + 10 + 12 + . . . . + 100 = 2550

Therefore, **2550** is the sum of first 50 even numbers.
