Answer 2

The answer to this puzzle is 29.

Step-by-step explanation:

We are given the following puzzle below;

1, 2, 5, 3 = 13

1, 4, 5, 6 = ?

1, 9, 5, 4 = 17

This given puzzle represents the pattern of;

[(C $\times$ D) - (A $\times$ B)] + k  {where k = 0 for first puzzle, 3 for second, and 6 for third}

Now, considering the first puzzle of 1, 2, 5, 3 = 13

Here, A = 1, B = 2, C = 5, and D = 3; also k = 0

So, [(5 $\times$ 3) - (1 $\times$ 2)] + 0

     = [15 - 2] + 0 = 13 + 0 = 13

Now, considering the third puzzle of 1, 9, 5, 4 = 17

Here, A = 1, B = 9, C = 5, and D = 4; also k = 6

So, [(5 $\times$ 4) - (1 $\times$ 9)] + 6

     = [20 - 9] + 6

     = 11 + 6 = 17

Now, considering the second puzzle of 1, 4, 5, 6 = ?

Here, A = 1, B = 4, C = 5, and D = 6; also k = 3

So, [(5 $\times$ 6) - (1 $\times$ 4)] + 3

     = [30 - 4] + 3

     = 26 + 3 = 29

Hence, the answer to ? is 29.
