TI-83 Plus Sequence Graphing 184
Using an initial value
u(
n
Min) = 1
, the sequence above returns
1
,
2
,
4
,
8
,
16
, . . .
Tip: On the TI-83 Plus, you must type each character of the terms. For
example, to enter
u(
n
N
1)
, press
y

Recursive sequences require an initial value or values, since they
reference undefined terms.
•
If each term in the sequence is defined in relation to the previous
term, as in
u(
n
N
1)
, you must specify an initial value for the first term.
•
If each term in the sequence is defined in relation to the term that
precedes the previous term, as in
u(
n
N
2)
, you must specify initial
values for the first two terms. Enter the initial values as a list enclosed
in braces ({ }) with commas separating the values.
The value of the first term is 0 and the value of the second term is 1 for
the sequence
u(
n
)
.
