This is in contrast to the definition of sequences of elements as functions of their positions. Sequences whose elements are related to the previous elements in a straightforward way are often defined using recursion. In mathematical analysis, a sequence is often denoted by letters in the form of a n, but it is not the same as the sequence denoted by the expression.ĭefining a sequence by recursion The first element has index 0 or 1, depending on the context or a specific convention. The position of an element in a sequence is its rank or index it is the natural number for which the element is the image. Sequences can be finite, as in these examples, or infinite, such as the sequence of all even positive integers (2, 4, 6. Also, the sequence (1, 1, 2, 3, 5, 8), which contains the number 1 at two different positions, is a valid sequence. The notion of a sequence can be generalized to an indexed family, defined as a function from an arbitrary index set.įor example, (M, A, R, Y) is a sequence of letters with the letter 'M' first and 'Y' last. Formally, a sequence can be defined as a function from natural numbers (the positions of elements in the sequence) to the elements at each position. Unlike a set, the same elements can appear multiple times at different positions in a sequence, and unlike a set, the order does matter. The number of elements (possibly infinite) is called the length of the sequence. Like a set, it contains members (also called elements, or terms). In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. For other uses, see Sequence (disambiguation).
