uTo 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, “an = An + B” is the general term (an = A × n + B) of {an}.
2. Press the function key for the recursion formula type you want to set.
•{a
n}/{an+1}/{an+2} ... {general term of sequence {an}}/{linear recursion between two
terms}/{linear recursion between three terms}
