Is it right or wrong that there is no largest odd or even number in natural number

Yes, it can be proved by the opposite method, assuming that x is the largest odd number, then x + 2 > x, and X + 2 is also an odd number, which contradicts the assumption that "x is the largest odd number"
No maximum even number can be proved
