Difference Between Sequence and Series

order following a particular set of rules. |
In series, the order of the elements is not
necessary. |
It is just a collection (set) of elements that
follow a pattern. |

Types of Series
Arithmetic Series
An Arithmetic Series is a series formed by using an arithmetic sequence. for example is an arithmetic series.
Geometric Series
A geometric Series is a sequence where every term bears a constant ratio to its preceding term. This ratio is called the "common ratio". The terms of the geometric sequence are of the form
Example: Here
Fibonacci Series
Fibonacci Series is a sequence where every term is the sum of the last two preceding terms.
