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
N1), press y [u] £ „ ¹ À ¤.
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
N1), 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
N2), 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
).
