A sequence is a set of numbers in a particular order. When you add the values in a sequence together, that sum is called a series! This tutorial introduces series and explains both finite and infinite series.

When you're looking at a sequence, each value in that sequence is called a term. This tutorial explains the definition of the term of a sequence. Take a look!
