Find the sum of the following series:
101 + 99 + 97 + … + 47
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
