Highlights and
Objectives
-
Distinguish
between infinite
sequences and finite
sequences.
-
a1, a2, a3, a4
,a5, a6 ,a7, ....... an are
the terms of the sequence
-
-
Find the
terms of an arithmetic
sequence using a formula.
-
Ex. Find the first five
terms of an = 2n - 1
(Unless otherwise stated, n starts with 1.)
-
A table can be used to generate the
sequence.

In
this example n is the domain and an
is the range.
This is how they are graphed
in sequence mode .
