``Re: Proof of Chebyshev's inequality by induction'' by vernondalhart on 2004-05-19 08:14:36
From a proper axiomatic standpoint, you're certainly correct. But while technically everything in mathematics should be derived from the axioms, this is often not really the case.

Really, I think his point was that if you can show something for an arbitrary integer $n$, then you've shown that it holds true for all $n$. I mean, if it only depends on that one value $n$ and on none of the $m \le n$, then that is basically a proof by induction, just a remarkably simple one.
