Then specify the direction of the sequence: increasing or decreasing, and the number you want to start from. Start by selecting the type of sequence: you can choose from the arithmetic sequence (addition), geometric sequence (multiplication), and the special Fibonacci sequence. This is a very versatile calculator that will output sequences and allow you to calculate the sum of a number sequence between a starting item and an n-th term, as well as tell you the value of the n-th term of interest. Our sequence calculator outputs subsequences of the specified sequence around the selected nth element. If each element is larger than or smaller than the preceding element, then a sequence is strictly monotonically increasing or strictly monotonically decreasing, respectively. Sequences can be monotonically increasing - that is if each term is greater than or equal to its preceding term, or they can be monotonically decreasing, if the reverse is true. Number sequences can be expressed as the function that generates the next term in a sequence from the previous one. The number of elements is the length of the sequence. ![]() In mathematics, a sequence is an ordered list of objects, usually numbers, in which repetition is allowed.
