0 or 1 as even or odd in GMAT

[focus1234]

Hi Folks,

At the onset, would like to wish the entire BTG community a Merry Christmas

Just came across a concept on which I need to clarify the following:

In a set of 3 consecutive multiples (x+1) (x) (x+2), where x is odd, the reference material considered 3 as odd instead of 1 - any reason for not considering 1 as odd?

Similarly, where x is even the same reference source considered 2 instead of 0 - why was 0 not considered as 0 is alsso an even?

Guys, pls help![spoiler][/spoiler]

Merry christmas!
zero is even and one is odd
not just in GMAT land, it is true everywhere
May be your reference source might have taken some examples to get to the answer.
But could you let us know whether the conditions or the question is failing for 0 & 1 or not?
If you could post the problem, it will be helpful for others as well.

0 is even and 1 is odd, no doubt.

THough, generally 0 and 1 are considered poor choices for substitution for multiple answer choices may satisfy given conditions for n=0 or 1.

Cannot clarify further without knowing the exact problem.

Hi Guys,

Thanks for the feedback....

The question stem is as follows:

If x^3-x=p, and x is odd, is p diivisible by 24?

Solution Hint: the author has factored x out of the expression to prove that x^3-x are consecutive integers
