What is the difference between finite series and infinite series?
A finite series always has a sum; an infinite series has one only if it converges (e.g. a GP with |r|<1).
A finite series always has a sum; an infinite series has one only if it converges (e.g. a GP with |r|<1). A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
