Sec. 13-1 Sequences
A sequence is a list of numbers. There are two kinds:
Arithmetic- +/- by the same number every term
Geometric- *// by the same number every term
Ex 6,4,2,0,... is Arithmetic
4,7,11,16,22,... is neither
To find the n^m term, you use these formulas:
Arithmetic- tn=t1+(n-1)d
Geometric- tn=t1*r
( d= the number that is used for A and G, the number being //+/-/*)
