TI-83 Plus Sequence Graphing 180
You can define sequence functions in terms of:
• The independent variable
n
• The previous term in the sequence function, such as u(
n
N1)
• The term that precedes the previous term in the sequence function,
such as u(
n
N2)
• The previous term or the term that precedes the previous term in
another sequence function, such as u(
n
N1) or u(
n
N2) referenced in the
sequence v(
n
).
Note: Statements in this chapter about u(
n
) are also true for v(
n
) and w(
n
);
statements about u(
n
N1) are also true for v(
n
N1) and w(
n
N1); statements about
u(
n
N2) are also true for v(
n
N2) and w(
n
N2).
Displaying the Sequence Y= Editor
After selecting Seq mode, press o to display the sequence Y= editor.
In this editor, you can display and enter sequences for u(
n
), v(
n
), and
w(
n
). Also, you can edit the value for
n
Min, which is the sequence
window variable that defines the minimum
n
value to evaluate.
