Let [z] mean the Greatest Integer less than or equal to z. Find a positive real number X, such that [X^n] is an even number whenever n is even, and [X^n] is an odd number whenever n is odd.
X=n.
When n is even, n^n is even. When n is odd, n^n is odd.
The only problem is that X, in this case, would not be a positive real number, it would be more than one positive real number, depending on what n is.
