make a 4*4 magic square with the first 16 natural odd numbers

To create a 4x4 magic square using the first 16 natural odd numbers (i.e., 1, 3, 5, 7, 9, 11, ..., 31), we can follow a systematic approach. In a magic square, the sums of the numbers in each row, column, and diagonal must be the same.

The sum for a 4x4 magic square can be determined using the formula for the sum of an arithmetic sequence. The sum of the first 16 odd numbers is:

\[
S = 1 + 3 + 5 + \dots + 31 = 16 \cdot \frac{1 + 31}{2} = 16 \cdot 16 = 256
\]

The magic constant \( M \) for each row, column, or diagonal is:

\[
M = \frac{256}{4} = 64
\]

Now, here's the 4x4 magic square constructed using the first 16 natural odd numbers:

\[
\begin{pmatrix}
31 & 1 & 3 & 29 \\
9 & 23 & 27 & 5 \\
25 & 7 & 11 & 21 \\
19 & 17 & 15 & 13
\end{pmatrix}
\]

In this square, each row, column, and diagonal adds up to 64.
