Is "ZERO" even or odd ?
neither



Wrong. Zero is an EVEN number but neither positive nor negative.

Since A,B,C are consecutive, one of them will be even and hence the product will also be. (1) alone is sufficient

2B = A + C => A+C is even. We do not know if one of them is even or not. Hence (2) alone is not sufficient.

Guys,

AkamaiBrah stated that "Zero" is EVEN. Can you prove that? Akamai, don't tell the solution yet.

The OG, thanks Stolyar for reviewing this often ignored concept.

The set of even integers is{ - 4, -2, 0, 2, 4, etc.}
Two claps for Bharti, too. He is using reasoning?
:wink:

Correct. 0 is an even integer, neither positive nor negative.

Definition of even # is that the # should be divisible by 2. Here is another definition:

"1. An even number when added to another even number will give an even number

2. An even number when added to an odd number will give an odd number"

Take any even number. Adding zero to it results in an even#=> zero is even.

Otherwise, take any odd #. Adding 0 to it results in an odd#. => zero is even.
