I found a $3 \times 3$ magic square and cannot figure out the missing digit. It is multiple choice (and just a game) but I want to know the pattern.
\begin{align*} 65 && 69 && 13\\ 14 && 63 && 22\\ 18 && ? && 17 \end{align*}
The possible answers are $78$, $85$, $98$, $51$. Thank you!
Interchange the digits in the entries of the first column. If you choose $98$ the columns of the resulting matrix are in a simple relation.
