Cantor's Rationals in Closed Form.

The article discusses a closed form expression for the nth term of a sequence that was developed based on an infinite-dimensional matrix used by mathematician Georg Cantor to establish the countability property of a set of positive rationals. Following Cantor's studies, many other enumerations of the rationals have been constructed such as one which used a systematic procedure to produce a listing of all positive rationals without duplication. It highlights the key properties of the matrix of rational numbers given to demonstrate another equation.
