cause the numbers go from 0----7 (that is 8 numbers)

so range of positive numbers are is 7-1=6...which is the OA...

0 is not a POSITIVE number...so exclude that...

let me see again

-4,-3,-2,-1,0 that would be 5 numbers

1,2,3,4,5,6,7 that would be 7 numbers

range is 7-1 equal to 6

ok, i finally got it

GMAT traps, so easy to fall on them

This question is from GMAT prep , my answer was incorrect. I missed the part range of positive integers

-4, -3, -2 , -1 , 0, 1, 2 ,3 4, 5 ,6 ,7. stop

So highest positive - lowest positive = range
7-1 = 6

The interesting thing is that GMATPrep gave me this question after 5 correct answers, so it should really be rated 700+ I think.

But I also had it wrong, as I answered 7, and not 6 (7-1 which is the range)

Best,

Solved it like a consecutive set problem.

X - - 4 / 1 + 1 = 12 ...
x +4 = 11 ...
x = 7.

Since 0 is not a positive integer, the range is 1-7. answer is 6, B.
