What is the median of a set of consecutive integers if the sum of nth number from the beginning and nth number from the end is 150? Choose one:  A) 10  B) 25  C) 50  D) 75  E) 100

Rationale: "surprisingly no one answered this easy one . property of a set of consecutive integerz . mean = median = ( first element + last element ) / 2 = ( second element + last but one element ) / 2 = ( third element + third last element ) / 2 etc . etc . so mean = median = 150 / 2 = 75 answer is d"
Answer: D
