# Find the sum of the following series:

101 + 99 + 97 + … + 47

Answer :

for the **given** AP the first term a is 101, and common difference d is a difference of second term and first term, which is 99 - 101 = - 2

**To find**: the sum of given AP

**The formula** for sum of AP is given by

Substituting the values in the above formula

s = 14 × 148

s = 2072
