Graph Function
u u u u u To enter the RECUR Mode
On the Main Menu, select the RECUR icon and enter the RECUR Mode. This

• All recursion formulas that are stored in memory appear in the Recursion
Menu.

• { SEL} ... {recursion formula generation/non-generation status}
• { DEL} ... {recursion formula delete}

n
and b
n
}
• { RANG} ... {screen for setting of table range}
• { TABL} ... {recursion formula table generation}
u u u u u To specify the recursion formula type
Before inputting a recursion formula, you must first specify its type.
1. In the Recursion Menu, press 3 (TYPE).
• In this display, “ a
n
= A n + B” is the general term ( a
n
= A × n + B) of { a
n
}.

• {a
n
} /{a
n+ 1
} /{a
n+ 2
} ... {general term of sequence {a
n
}}/{linear recursion between two
terms}/{linear recursion between three terms}
