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
).
