Infinity is not a number. It really means "unbounded" -- that is, there is no limit.
Suppose that infinity is a number. Assign X to be infinity. Then since X is a number, then X+1 exists and is also a number. However, then X cannot be infinity.
Thus infinity is not a number. Since infinity is not a number, it is neither even nor odd.
This. Infinity is, for some purposes, treated as a 'quasi-number', but it is not formally a number and shouldn't be thought of as one, but rather the lack of a limit.
