Reciprocal of the terms gives you 1, ½, ⅓, ¼, …. Harmonic Sequence:Ī harmonic sequence represents the reciprocal of the terms present in an arithmetic sequence.įor example, 1, 2, 3, 4,…. Geometric Sequence:Ī sequence in which the ratio between the element and the preceding element continues to be constant is a geometric sequence.Īn example of a geometric sequence is 1, 4,16,64,…… The first difference between the number and its preceding numbers is 1, 2, 3, and 4.īut the second difference between elements and their preceding element is 1. In quadratic sequence, the second difference is the same. In an arithmetic sequence, the difference between the preceding elements is the same. Now that you know the arithmetic sequence, you can understand the quadratic sequence. The fixed number added to the preceding number is called the common difference. Arithmetic Sequence:Ī number sequence in which every element is the addition of the previous element with a fixed number is an arithmetic sequence. Read further to know these types of number sequences. Other than these types, there can be other number sequences.
There are a few types of number sequences that have a specific pattern. The number of sequences for which the number of elements is not finite, the sequence is said to be an infinite sequence. Finite sequences are the ones where you can determine the number of elements in the number sequence.
