In this unit we learned about Arithmetic Sequences and Series and Geometric Sequences and Series.

Sequence- list
Series- sum

Arithmetic- common ratio is addition
Geometric- common ratio is multiplication

a- first term
r- common ratio
d- common difference
t- term
tn- term number
sn- sum number

converge- ratio decreases -1<r<1
diverge- ratio increaces r>1   r<-1

converge- infinite sum S∞
