1. On the Y= Editor (
8 #
), define u1(n) = 3.2u1(n
N
1)
N
.8(u1(n
N

. Set initial value
ui1 = 4.45.
2. Set
Axes = TIME
.
3. On the Window Editor (
8 $
), set the Window variables.
5. On the Y= Editor, set
Axes = WEB
and
Build Web = AUTO
.
6. On the Window Editor (
8 $
), set the Window variables.

4. Graph the sequence (
8 %
).
Because the sequence quickly
diverges to large negative values,
only a few points are plotted.
