[RESOLVED] Magic square, 5x5, even numbers from 2 to 50 totalling 130

You can of course just halve all the entries to get a more traditional puzzle. Here's a solution to that version. Here's a Wikipedia page discussing the general method; perhaps your son was supposed to use it in this case himself.

Edit: I remembered that I dislike it when mathematicians aren't explicit when they easily could be, so here's an explicit solution:

34 48  2 16 30
46 10 14 28 32
 8 12 26 40 44
20 24 38 42  6
22 36 50  4 18
