A sequence number is a consecutive number in a sequence of numbers, usually of real integers (natural numbers).Sequence numbers have many practical applications. They can be used, among other things, as part of serial numbers on manufactured parts, in case management, [1] or in databases as a surrogate key for registering and identifying unique entries in a table [2] [3] (in which case it is ...
The nth element of a Fibonacci word, , is 1 if the Zeckendorf representation (the sum of a specific set of Fibonacci numbers) of n includes a 1, and 0 if it does not include a 1. The digits of the Fibonacci word may be obtained by taking the sequence of fibbinary numbers modulo 2. [10]
The Oxford English Dictionary derives the numero sign from Latin numero, the ablative form of numerus ("number", with the ablative denotations of "by the number, with the number"). In Romance languages, the numero sign is understood as an abbreviation of the word for "number", e.g. Italian numero, French numéro, and Portuguese and Spanish ...
Page number in a book. Page numbering is the process of applying a sequence of numbers (or letters, or Roman numerals) to the pages of a book or other document. The number itself, which may appear in various places on the page, can be referred to as a page number or as a folio. [1]
Numbers written in different numeral systems. A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems.
There are a number of ways to denote a sequence, some of which are more useful for specific types of sequences. One way to specify a sequence is to list all its elements. For example, the first four odd numbers form the sequence (1, 3, 5, 7). This notation is used for infinite sequences as well.

If s is an infinite sequence word and w is a finite word, let μ N (w) denote the number of occurrences of w as a factor in the prefix of s of length N + |w| − 1. If μ N (w) has a limit as N→∞, we call this the frequency of w, denoted by μ(w). [4]: 73 For a Sturmian word s, every finite factor has a frequency.
