What is the difference between a sequence and a series?
The list of numbers written in a definite order is called a sequence. The sum of terms of an infinite sequence is called an infinite series. A sequence can be defined as a function whose domain is the set of Natural numbers. Therefore sequence is an ordered list of numbers and series is the sum of a list of numbers.
Example of a sequence:
2, 4, 6, 8, 10 …
Now if we add them up:
This is a series.
