In mathematics, a sequence is an ordered list of objects. Accordingly, a number sequence is an ordered list of numbers that follow a particular pattern. The individual elements in a sequence is often referred to as term, and the number of terms in a sequence is called its length, which can be infinite. In a number sequence, the order of the sequence is important, and depending on the sequence, it is possible for the same terms to appear multiple times. There are many different types of number sequences, three of the most common of which include arithmetic sequences, geometric sequences, and Fibonacci sequences.
