Best Answer

It appears that each column uses the same algebraic expression on the first 3 numbers, with the last row being a total.

First Column: (6 x 4) - 6 = 18
Second Column: (7 x 3) - 11 = 10
Third Column: (9 x 2) - 5 = 13

So, for the fourth column, using the same pattern, you'd have:

(16 x 4) - 32 = ?

64 - 32 = 32.
