Given positive integer n, consider the set of numbers {n²+1, n²+2, ... (n+1)²}. If we pick two numbers x and y out of that set, how many different values can the product xy take?

(In reply to re(3): what am I missing? by owl)

How about the sequence {1,2,3,4,5,6}?

How do you achieve this sequence? For what value of n?
