Sequences are ordered lists of elements, typically numbers, arranged according to a specific rule or pattern. Each element in a sequence is called a term and has a defined position, usually indicated by an index. Sequences can be finite or infinite and may follow arithmetic, geometric, or more complex rules. They play a fundamental role in mathematics, especially in analysis, number theory, and combinatorics, and are used to model processes that evolve step by step. In everyday contexts, sequences can also refer to ordered sets of events, actions, or items arranged in a meaningful or logical order.
