Move Up 1 and Right 1 wrapping both vertically and horizontally when you leave the grid * (see note below). If that square is empty enter the next number; if the square is not empty put the next number underneath the last number you entered. Repeat 2&3 until the grid is complete. All rows, columns and the two diagonals will sum to the same value.
How to find the number of rows in a magic square?
You can find this number by using a simple math formula, where n = the number of rows or columns in your magic square. So, for example, in a 3×3 magic square, n = 3. {displaystyle m=n [ (n^ {2}+1)/2]}.
How to get 15 as a sum of 3 numbers?
Another approach is to consider the ways to obtain 15 as a sum of 3 different numbers in the range 1..9. These are: 1+5+9, 1+6+8, 2+4+9, 2+5+8, 2+6+7, 3+4+8, 3+5+7, 4+5+6. As you can see there are only 8 ways, and you need 8 different sums in your square. So each sum appears exactly once as a line in your square.
How to put numbers 1 to 9 in 3×3 grid?
In a 3×3 grid, I’d have to put numbers from 1 to 9 in a manner so that respective row, column and diagonal add up to 15. I have only been able to come up with one solution:

Where is number 15 in the 5×5 grid?
If you look at the example of the 5×5 at number 15. The next position is the square up and to the right of 15 which wraps on both the row and column to point to the lower right square which has 11 in it. As that square is not empty we placed 16 underneath 15. Thank you @ Alan for explaining it so well and generalising it.
How to find the number of squares inside the given grid?
Approach 1: Taking a few examples, it can be observed that for a grid on size N * N, the number of squares inside it will be 12 + 22 + 32 + … + N2 Approach 2: By the use of direct formula.
How to fill 8 numbers in grid with given conditions?
Place the numbers 1, 2, 3, 4, 5, 6, 7, 8 into the eight circles in the figure given below, in such a way that no number is adjacent to a number that is next to it in the sequence. For example, 1 should not be adjacent to 2 but can be adjacent to 3, 4, 5, 6, 7, 8.
