If 'n' is a natural number such that n>1, prove that there exists a natural number k such that n-k=1.(adsbygoogle = window.adsbygoogle || []).push({});

It raises the question: What is the definition of a natural number?

Could you say that because n is natural, n-1 must be natural so that if k = n-1, n-k = 1?
