From entry sequence in glossary Artificial Intelligence: humans at the heart of algorithms
A sequence is an ordered collection of values. In a time series these are each attached to a particular point of time, but they may also simply be ordered, for example [2,3.7,12,8,3.2 ..]. A sequence can be finite, but may be unbounded or of unknown future length. Sequential data might be numeric, but also of any data type.
