The <ahref="https://en.wikipedia.org/wiki/Look and say sequence"target="_blank">Look and say sequence</a> is a recursively defined sequence of numbers.
Sequence Definition
<ul><li>Take a decimal number</li>
<li><span>Look</span> at the number, visually grouping consecutive runs of the same digit.</li>
<li><span>Say</span> the number, from left to right, group by group; as how many of that digit there are - followed by the digit grouped.</li></ul><span> This becomes the next number of the sequence.</span>
<span>An example:</span>
<ul><li>Starting with the number 1, you have <span>one</span> 1 which produces 11</li>
<li>Starting with 11, you have <span>two</span> 1's. I.E.: 21</li>
<li>Starting with 21, you have <span>one</span> 2, then <span>one</span> 1. I.E.: (12)(11) which becomes 1211</li>
<li>Starting with 1211, you have <span>one</span> 1, <span>one</span> 2, then <span>two</span> 1's. I.E.: (11)(12)(21) which becomes 111221</li></ul>
