EMNA Q.24
0. What is the maximum sum of the series 60, 58, 56, 54, 52, ?
- Option : C
- Explanation :
Since d = -2, maximum sum of the series will be sum of all the positive terms.
Least positive term of the series is 2 or 0 (both giving equal sum)
Let, 2 be the nth term
2 = 60 + (n 1) - 2
=> n = 30
Required sum = 30/2 (60 + 2) = 930
