I doubt that Mathematica can do this, since it cannot even do the following:

Reduce[ForAll[k,
  Element[k, PositiveIntegers],
  Element[2^k, Integers]]]

or this:

Reduce[ForAll[k,
  Element[k, PositiveIntegers],
  Element[1/k, Integers]]]

I am thinking that the combination of Floor and Log is making this difficult. Is there any way that you could eliminate those and write the problem in terms of 2*n+1<2*n+1+1<2*(n+1)+1 and from that the conclusion must be True?
