Wrt the strict rules of the evens: { 2, 4, 6, 8, ... } And the naturals: { 1, 2, 3, 4, ... } there is are no gaps between them. Wrt the evens there is no even between 2 and 4. Wrt naturals there is no number between 1 and 2. Strictly speaking, of course. The evens: { 1*2, 2*2, 3*2, 4*2, ... } The naturals and the evens are all showing.
