What is the graph of the sequence An = (-1)^n?
n = 0 then A(n) = 1
n = 1 then A(n) = -1
n = 2 then A(n) = 1
n = 3 then A(n) = -1
The graph will continue from 1 to -1 indefinitely.
The same thing will happen for n<0.
n = 1 then A(n) = -1
n = 2 then A(n) = 1
n = 3 then A(n) = -1
The graph will continue from 1 to -1 indefinitely.
The same thing will happen for n<0.
