Description html markup shown to student	<p>An instructor believes she teaches better each semester and aims to prove it by entering the average final exam score for each semester in order up through the current semester, entering <tt>-1</tt> upon completion. Your program should check that the values entered are increasing (always larger than the previous value).</p> <p></p> <p>If her belief is true, output <tt>True</tt>. If it is not true, output <tt>False</tt> and <strong>do so as early as the data reveals the belief is false</strong>.</p> ​ ​
