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
