Example Generate a number table from recursion between three terms as
expressed by
an+2 = an+1 + an, with initial terms of a1 = 1, a2 = 1
(Fibonacci sequence), as n changes in value from 1 to 6.

#Pressing 1(FORM) will return to the screen
for storing recursion formulas.
* The first two values correspond to
a1 = 1 and a2 = 1.
# Specifying On for the Σ Display of the Setup
screen causes the sum of each term to be
included in the table.
