Graphing a Recursion Formula
Example Generate a number table from recursion between two terms as
expressed by
an+1 = 2an+1, with an initial term of a1 = 1, as n changes
in value from 1 to 6. Use the table values to draw a line graph.
Use the following V-Window settings.
Xmin = 0, Xmax = 6, Xscale = 1
Ymin = –15, Ymax = 65, Yscale = 5
