Here is this week’s problem:
Z is the set of the first n positive odd numbers, where n is a positive integer. Given that n> k, where k is also a positive integer, x is the maximum value of the sum of k distinct members of Z, and y is the minimum value of the sum of k distinct members of Z, what isx + y?
