    How to Find the Sum of First 200 Even Numbers?

    The below workout with step by step calculation shows how to find what is the sum of first 200 even numbers by applying arithmetic progression. It's one of the easiest methods to quickly find the sum of given number series.
    step 1 Address the formula, input parameters & values.
    Input parameters & values:
    The number series 2, 4, 6, 8, 10, 12, .  .  .  .  , 400.
    The first term a = 2
    The common difference d = 2
    Total number of terms n = 200

    step 2 apply the input parameter values in the AP formula
    Sum = n/2 x (a + Tn)
    = 200/2 x (2 + 400)
    = (200 x 402)/ 2
    = 80400/2
    2 + 4 + 6 + 8 + 10 + 12 + .  .  .  .   + 400 = 40200

    Therefore, 40200 is the sum of first 200 even numbers.
