👉 Unperiodical is a phrase used in mathematics and computer science to describe a sequence or function that does not repeat its values after a certain length of time. It is often used to describe sequences where each element is different from the previous one, but there are no consecutive elements sharing the same value. For example, consider the following sequence: 1, 2, 3, 4, 5. In mathematics and computer science, unperiodical sequences can be defined in terms of recurrence
