The constant is 34.
A 3x3 magic square has the property that the sum of the numbers in each row, column, and diagonal is the same. For a 3x3 magic square using the numbers 1 to 9, the magic constant is 15, not 18. If you're referring to a different set of numbers or a modified version of a magic square, please specify the numbers used to achieve a magic constant of 18.
In an 8x8 magic square, the sum of each row, column, and diagonal is the same, known as the magic constant. For an n x n magic square, the magic constant can be calculated using the formula ( M = \frac{n(n^2 + 1)}{2} ). For an 8x8 magic square, this gives ( M = \frac{8(64 + 1)}{2} = 260 ). Therefore, the sum in the 1st row of an 8x8 magic square is 260.
A magic triangle is a numerical arrangement similar to a magic square, where numbers are placed in a triangular format instead of a square grid. In a magic triangle, the sums of the numbers along each side of the triangle and sometimes along certain diagonals are equal to a constant known as the magic constant. While magic squares typically feature rows and columns, magic triangles focus on the triangular configuration and its properties. Both concepts are part of recreational mathematics and explore the relationships between numbers in unique ways.
Magic squares have been a source of intrigue since the time of Pythagoras, and even before. You will find the following link useful.
MAGIC SQUARE is a square divided into equal squares, like a chess board, where in each individual square is placed one of a series of consecutive numbers from 1 up to the square of the number of cells in a side, in such a manner that the sum of the numbers in each row or column and in each diagonal is constant.

A magic square is a grid of numbers arranged in such a way that the sums of the numbers in each row, column, and both main diagonals are equal. This common sum is known as the magic constant. Magic squares can vary in size, with the smallest being 3x3, and they have been studied in mathematics for centuries due to their intriguing properties and patterns. They often appear in recreational mathematics and art, symbolizing harmony and balance.

A 5x5 magic square is a grid filled with distinct integers from 1 to 25, arranged so that the sum of the numbers in each row, column, and both main diagonals equals the same magic constant, which is 65 for a 5x5 square. There are numerous configurations for a 5x5 magic square, with the most common methods including the Siamese method and the Strachey method. Each valid arrangement will meet the criteria of having unique integers and achieving the same sum across all rows, columns, and diagonals. There are 880 distinct 5x5 magic squares when accounting for rotations and reflections.
Just take any magic square, and multiply every number by 5. Here you will get another magic square with all numbers multiples of 5.
Think! What if the magic square had an even number of cells. There's your answer.
