Fun Math Riddle: Find the Missing Number in the Table

The number in the 3rd column is the sum of the addition and multiplication of the numbers in 1st and 2nd column.

So we can check the numbers as;

(5 + 2) + ( 5 x 2) = 7 + 10 = 17

(7 + 3) + (7 x 3) = 10 + 21 = 31

(3 + 4) + (3 x 4) = 7 + 12 = 19

(4 + 8) + (4 x 8) = 12 + 32 = 44

So we can find the missing number as;

(11 + 12) + (11 x 12) = 155

Answer = 155
