Examples: {1, 2, 3, 4, ...} is a very simple sequence (and it is an infinite sequence) {20, 25, 30, 35, ...} is also an infinite sequence. {1, 3, 5, 7} is the sequence of the first 4 odd numbers (and is a finite sequence) {4, 3, 2, 1} is 4 to 1 backwards. {1, 2, 4, 8, 16, 32, ...} is an infinite sequence where every term doubles.
Sequences are a special type of function that are useful for describing patterns. In this unit, we'll see how sequences let us jump forwards or backwards in patterns to solve problems. Introduction to arithmetic sequences

Sequence. In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms ). The number of elements (possibly infinite) is called the length of the sequence.
6 de oct. de 2021 · Sequences. A sequence 1 is a function whose domain is a set of consecutive natural numbers beginning with \(1\). For example, the following equation with domain \(\{1,2,3, \dots\}\) defines an infinite sequence 2: \(a(n)=5 n-3\) or \(a_{n}=5 n-3\) The elements in the range of this function are called terms of the sequence.
Cómo funcionan las fórmulas explícitas. Esta es una fórmula explícita de la sucesión 3, 5, 7, …. a ( n) = 3 + 2 ( n − 1) En la fórmula, n es cualquier número de término y a ( n) es el é n ésimo término. Esta fórmula nos permite simplemente sustituir el número del término que nos interesa, y obtendremos el valor de ese término.
Sequences are ordered lists of numbers (called "terms"), like 2,5,8. Some sequences follow a specific pattern that can be used to extend them indefinitely. For example, 2,5,8 follows the pattern "add 3," and now we can continue the sequence. Sequences can have formulas that tell us how to find any term in the sequence.
