👉 Unrecurrent, also known as a "non-recurrent" or "discrete" sequence, is a type of sequence where each element in a sequence is preceded by its predecessor. In other words, the next element after a previous one is not followed by any preceding elements. For example: - The first element (0) is 0. - The second element (1) is 1. - The third element (2) is 2. - The fourth element (3)
