An '''abundant number''' is any number, '''''n''''', which has a [[sigma|sigma value]] greater than '''''2n'''''.<br />
<br />
==Example==<br />
The divisors of 12 are <math>(1, 2, 3, 4, 6, 12)</math>, so<br />
:<math>\sigma(12)\ =\ 1+2+3+4+6+12\ =\ 28</math><br />
<br />
==Abundant numbers and aliquot sequences==<br />
Abundant numbers increase the size of an [[aliquot sequence]] because when an abundant number occurs in a sequence, the next step is larger than the current step. Also, when a sequence is controlled by a driver, the subsequent steps are always abundant until an escape from the driver is obtained.<br />
