The following are the smallest 9 elements of an infinite set of integers:
0,1,5,6,25,76,376,625,9376
What rule generates the set? What are the next two values?

quite clever Bryan.
Just as a note to you, your answer is quite valid (even though it may not be the intended one). You found a rule which correctly calculates the series to the limit given, and that's all you can hope to do. In fact, that is one of the largest hurdles when creating a series puzzle, as you have to give the solvers enough terms so that duplicate "rules" are not likely, but giving too many will often make the solution prohibitive, obvious or irrelevant.
