Look at the colmuns going down... do you see a pattern?

take the number in the first row and add 6... this provides the number for the second row

with the number from the second row, subtract five

Now just plug in formula to find M and N

m=4
n=1

This tests the ability to spot patterns, if it is on GMAT PREP it may show up on GMAT...

Probably the way it is posted here added to the misery. Is there a concept such as Addition table subtraction table in Math?? Not that I knew of until now

Since, the question is from GMATPrep and GMATPrep contains all the retired real GMAT questions, I assume questions with similar concepts may appear in live GMAT.

BTW, when I encountered this question during one of my GMATPrep tests, I kept staring at it for about 2 minutes just to understand what it really is asking for

yeah exactly ... it came to me as 2nd questins and I wasted around 4-5 mins to find out that the hell is this addition table... and then ended up randomly choosing the answer. I guess I should have atleasted realized the pattern.
