Question

Below is a magic square, meaning that the sum of the numbers in each row, in each column, and in each of the 2 main diagonals are equal. What is the value of n?

Answer 1

• Basically, in a 3 × 3 magic square, the sum of the numbers in each row, in each column, and in each of the 2 main diagonals, is 15.
• So, let us consider the first row.
• (n + 2) + 1 + n = 15
• or, 2n + 3 = 15
• or, 2n = 15 - 3
• or, 2n = 12
• or, n = 6

Answer:

The value of n is 6.
