MTH133 Lab 5: Pre-Lab Learning Goals In class, typical examples of divergent sequences and series are those whose values fly off to infinity. In real life, however, divergence is more frequently associated with meandering behavior that doesn't fly off to infinity but also doesn't settle down toward one number. The simplest example of this is the eyclical behavior of the sequence 2 1,-1,1, 1, 1,-1,... which remains always bounded but nevertheless does not converge.
