The largest number in each column is always the sum of the three smaller numbers.

6 + 3 + 6 = 15 6+3+6=\boxed{15}

(In the bottom row, this is also true, but it doesn't seem intended.)

@Crystal Gupta you can also take the following LaTeX code instead of the picture, if you want

\begin{array}{cccc}
13 & 4 & 4 & {\color{red}?} \
4 & 2 & 4 & 6 \
5 & 12 & 8 & 13 \
4 & 6 & 16 & 6
\end{array}


You then also have to place \( before and \ ) after the code, but without the spaces. It will look like the following

\( \begin{array}{cccc} 13 & 4 & 4 & {\color{red}?} \\ 4 & 2 & 4 & 6 \\ 5 & 12 & 8 & 13 \\ 4 & 6 & 16 & 6 \end{array} \)
