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
N
1)
•
The term that precedes the previous term in the sequence function,
such as
u(
n
N
2)
•
The previous term or the term that precedes the previous term in
another sequence function, such as
u(
n
N
1)
or
u(
n
N
2)
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
N
1)
are also true for
v(
n
N
1)
and
w(
n
N
1)
; statements about
u(
n
N
2)
are also true for
v(
n
N
2)
and
w(
n
N
2)
.
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.
