1,4,9,16,25
&lt;pre&gt;
a&lt;sub&gt;1&lt;/sub&gt; =  1 = 1&lt;sup&gt;2&lt;/sup&gt;
a&lt;sub&gt;2&lt;/sub&gt; =  4 = 2&lt;sup&gt;2&lt;/sup&gt;
a&lt;sub&gt;3&lt;/sub&gt; =  9 = 3&lt;sup&gt;2&lt;/sup&gt;
a&lt;sub&gt;4&lt;/sub&gt; = 16 = 4&lt;sup&gt;2&lt;/sup&gt;
a&lt;sub&gt;5&lt;/sub&gt; = 25 = 5&lt;sup&gt;2&lt;/sup&gt;
...

So the nth term is n&lt;sup&gt;2&lt;/sup&gt;

a&lt;sub&gt;n&lt;/sub&gt; = n&lt;sup&gt;2&lt;/sup&gt;
