Definition (2) A fallacy based on an attempt to use a statistically insignificant example to prove something. Mathematical statements are exactly the same as fashion statements. Proof theory is a major branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques.

That step is absolutely fine if we can later prove it is true, which we do by proving the adjacent case of P (k + 1).
