Answer 1

Answer:

1225

Step-by-step explanation:

address the formula, input parameters & values.

Input parameters & values:

The number series 1, 2, 3, 4, . . . . , 48, 49.

The first term a = 1

The common difference d = 1

Total number of terms n = 49

step 2 apply the input parameter values in the formula

Sum = n/2 x (a + Tn)

= 49/2 x (1 + 49)

= 2450/2

1 + 2 + 3 + 4 + . . . . + 48 + 49 = 1225

Therefore, 1225 is the sum of positive integers upto 49
