Sekuens

Sekuens is a term used in several languages to denote an ordered collection of elements in which the position of each element matters. A sekuens can be finite or infinite and may be defined by explicit rules or by recurrence. The concept appears across disciplines, including mathematics, computer science, biology, and linguistics.

In mathematics, sekuens refers to an ordered list of objects, such as numbers or functions. It can be defined explicitly or recursively. Common examples are arithmetic sequences, where consecutive terms differ by a constant, and geometric sequences, where consecutive terms share a constant ratio. Infinite sequences may converge to a limit, diverge, or oscillate.

In computing, a sekuens is an ordered collection such as a string, array, or list. Operations include indexing, concatenation, slicing, and iteration. Sequences underpin areas like data processing, pattern matching, and sequence alignment in bioinformatics.

In biology, genetic and protein sequences describe the order of nucleotides or amino acids. DNA and RNA sequencing technologies determine this order, enabling genome assembly, annotation, and comparative analysis. In linguistics, sequences describe ordered phonemes, syllables, or morphemes, while in media, sequels or sequential works describe related installments.

Sekuens derives from Latin sequentia and the English sequence; in some languages it is used as a direct loanword for the mathematical or computational concept.
