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

Result Screen

#You can make the number table active by pressing K1(CHNG) or A.

#After drawing a graph, you can return to the number table screen by pressing !6(GT) or A.
