step 1 address the formula, input parameters & values.
Input parameters & values:
The number series 1, 2, 3, 4, . . . . , 49, 50.
The first term a = 1
The common difference d = 1
Total number of terms n = 50
step 2 apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= 50/2 x (1 + 50)
= 2550/2
1 + 2 + 3 + 4 + . . . . + 49 + 50 = 1275
Therefore, 1275 is the sum of positive integers upto 50
