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 plot line graph with
ordinate Σ
a n , abscissa n .
Use the following V-Window settings.
Xmin = 0, Xmax = 6, Xscale = 1
Ymin = –15, Ymax = 65, Yscale = 5
