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

    My son got an assignment and I am trying to help him solve it but I am also unable to find the solution, can anyone here help me out? Google was not helpful also. He has got to solve a magic square and there is already a hint as seen in the attached image. All the diagonals (X), verticals and horizontals should have a sum of 130. Thanks for any tip!

    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:
    Code:
    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

    Thanks, it was an assignment but the teacher did not teach them any method in finding the answer. I am now trying to learn that method in the link you provided, thank you so much!
