Answer 2

Answer:

step 1 address the formula, input parameters & values.

Input parameters & values:

The number series 1, 2, 3, 4, . . . . , 999, 1000.

The first term a = 1

The common difference d = 1

Total number of terms n = 1000

step 2 apply the input parameter values in the formula

Sum = n/2 x (a + Tn)

= 1000/2 x (1 + 1000)

= 1001000/2

1 + 2 + 3 + 4 + . . . . + 999 + 1000 = 500500

Therefore, 500500 is the sum of positive integers upto 1000.
