👉 In mathematics, a subsequence of a sequence is a sequence that can be derived from another sequence by deleting some or all elements without changing their order. For example, in the sequence 1, 2, 3, 4, 5, the subsequence 2, 4, 5 can be obtained by removing 1 and 3. The term "subsequence" is often used to describe a particular part of a larger sequence that may be considered as a whole.
