MATH 2B - Lecture 18 - Sequences
Sequence - a list of infinite numbers written in a definite order
Notations - 
or  or 
Example:
 can be denoted as:

Divergence & Convergence
A sequence  is convergent, if 
, L is a finite number
Otherwise, we say  is divergent
Basically, we try to find the general formula for a sequence, , then try to
find 


If 
 is finite  is convergent. Otherwise,  is divergent
Example:
Determine whether
 is convergent
Solution:





