You won't get an answer from mared. (S)he only wants full answers without having to do any work. If a full solution isn't posted you are guaranteed to be ignored.

(differences: 2, 1, 0, -1, ...) amounts to soroban's solution. If it's a decent problem, there's a simpler answer that I haven't found.
