How to Find the Sum of First 10000 Even Numbers?
The below workout with step by step calculation shows how to find what is the sum of first 10000 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, . . . . , 20000.
The first term a = 2
The common difference d = 2
Total number of terms n = 10000
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 10000/2 x (2 + 20000)
= (10000 x 20002)/ 2
= 200020000/2
2 + 4 + 6 + 8 + 10 + 12 + . . . . + 20000 = 100010000
Therefore, 100010000 is the sum of first 10000 even numbers.
