The sum of k consecutive integers is 51. If the least integer is -50, then k =
Correct answer: E
Explanation
The difference is consistent with each integers , therefore the series can be A.P.
Sum of A.P. = A + (N-1) D
A=First term
D=Difference between each integer
N=number of terms
Sum = A + (N - 1 ) D
51= -50 + N - 1
N = 102
Answer = E
