Question

Find the missing number 9(3) (4) (3)
(5) (1) (2) (7) (2) (?)

Answer 1

Answer:

It is very easy.

First of all subtract the numbers horizontally and then find the product of their differences.

Don't be bothered of negative sign, you've to concerned with mod of the difference.

Let say for the first case: (12 - 4) x (7 - 3) = 8 x 4 = 32. (i.e. the number at the centre.)

Similarly for the second case: (11 - 5) x (8 - 1) = 6 x 7 = 42.

Finally for the third case: (9 - 6) x (3 - 2) = 3 x 1 = 3 (Ans)
