I'm a bit stuck on Question 42, Level 5, which has the following number puzzle:

53 (3) 59
92 (4) 98
34 (2) 38
71 (?) 79

I know I need to solve for the question mark, but I'm not sure what the pattern is or even where to start. Does anyone know what to do?

If you have numbers X, Y, and Z, it looks like the trick is to

multiply the second digit of X by Y then append the result to the first digit of X to get Z.
50 + (3 * 3) = 59
90 + (2 * 4) = 98
30 + (2 * 4) = 38

If this is the case, the answer is

? = 9

9.

Take the last digit of the numbers and divide the right number by the left one.

53 (3) 59 -> 3 9 -> 9 / 3 = 3  
92 (4) 98 -> 2 8 -> 8 / 2 = 4  
34 (2) 38 -> 4 8 -> 8 / 4 = 2  
71 (?) 79 -> 1 9 -> 9 / 1 = 9
