Chapter 13-1

Sequences-
is a list of numbers. There are two kinds of sequences:

1) Arithmetic- +/- by the same number every term
2) Geometric- *// by the same number every term

Ex: if tsubnl=4n-3, find the first 4 terms:

tsub1=4(1)-3=4-3=1
tsub2=4(2)-3=8-3=5
tsub3=4(3)-3=12-3=9
tsub4=4(4)-3=16-3=12
arithmetic +4

Well, I'm done.
