Pattern, Pattern, Where For Art Thou Pattern?

It's Friday and that means it is time for another problem of the week.  I had so much fun toiling over all my choices for problems and pondering which math problem I should unleash upon you!  BWAHAHAHAHAHA!  (Perhaps that was overdoing it a bit.)

Anyway, I have chosen one for you in which you must identify a pattern.  In my experience, either you see the pattern right away and wonder what all the fuss is about, or you stare blankly at it for hours on end unable to identify the pattern (Pattern? I don't see no stinking pattern...).  Ok, so I would probably be the only one to spend hours trying to solve a problem, but you get the point.

So without further ado, here is your problem.

Pattern

Look for a pattern and then find the number that should be used in place of the question mark in the following array of numbers:

7   4   2   6

8   2   4   3

5   3   5   7

9   ?   2   8

Feel free to tell my what the pattern is and the missing number in the comment sections below.  I will post the answer on Sunday.  Don't you be cheaters and look at the comment section for the answer.  ;)
