All/Any different? (Posted on 2005-08-16) Difficulty: 4 of 5
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: what am I missing? by owl)

owl, my thought is that in a sequence of integers, if you take the first term and multiply by all the others, then the second, then the third,... there´s no way to achieve the same product in two multiplications.

But, since it is too easy, my subject was "what am I missing?".
