<p><span style="font-family:Arial, Helvetica, sans-serif;">The statement is true for n = k + 1. By the principle of mathematical induction, the statement is true for all positive integers n.</span></p>

<h2><span style="font-family:Arial, Helvetica, sans-serif;">Variation</span></h2>
<p><span style="font-family:Arial, Helvetica, sans-serif;">There were cases where proof for each positive integer was needed, instead of all the integers.</span></p>

<p><span style="font-family:Arial, Helvetica, sans-serif;">When n is in a range.</span></p>
<p><span style="font-family:Arial, Helvetica, sans-serif;">For all positive odd integers n.</span></p>
