Recursive Sequences

This program gives a graphical and numerical representation of recursively-defined sequences. 1,2,3…n is stored to L1, while A[sub](k+1) as a function of A[sub]k is stored to L2. The sequence is plotted against its term number (in a graph situation), though reading off L2 for the sequence is more handy (especially for busy-work). The graphs are interesting, however; the graph of A[sub](k+1)=3A[sub]k, for example, increases like a geometric sequence with a common ratio r=3.
