Hi All,

Can someone please tell what all are the consecutive integers of 3 ?

a) only 2
b) only 4
c) or both 2 and 4.

if C, then does it mean that consecutive mean we need to see in both the directions ?

Thanks
Mohit

I don't think I've heard the expression "consecutive integers of 3" before (I've certainly never seen an official question use this expression). I'm not sure what it's supposed to mean. I can tell you that:
2,3 are consecutive integers
3,4 are consecutive integers
2,3,4 are consecutive integers

I don't know that answers your question.

Hi Brent,

Thanks.

Basically what my doubt is....is consecutive integer of N means N +1 or it means N -1 too....

Basically do we need to think in both directions when asked for a consecutive integer of N ?

Many Thanks
Mohit

Please see the link. n-1 and n (2,3), n and n+1 (3,4) ARE consecutive integers, however n, n-1 (3,2) ARE NOT. I hope that helps.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
