Sequence- is a list of numbers that are related to each other by a rule. The numbers in a sequence are called the terms. Example: $1,3,5,7,9,\ldots$ All these numbers form a sequence because the difference between two consecutive numbers in$2$. This type of sequence in which the difference between two terms is constant called Arithmetic sequence.
