Unit 7 - Sequences

This unit focuses on the concept of sequences. This course includes Chapter 7 section 1 (not including factorials), and parts of section 2 and 3 as outlined below.

    Follow this link for a list of Graphing Calculator Skills needed for this chapter.


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.
n an an  
1 2(1) - 1 1
2 2(2) - 1 3
3 2(3) - 1 5
4 2(4) - 1 7
5 2(5) - 1 9

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