Example Generate a number table from recursion between two terms as
expressed by
a n +1 = 2 a n + 1, with an initial term of a 1 = 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

Graphing a Recursion Formula
# After drawing a graph, you can use Trace,
Zoom, and Sketch.
# After drawing a graph, you can return to the
number table screen by pressing !6 (G ↔ T)
or A .
