The Number Sequence That Describes Itself

This sequence generates numbers by reading aloud the digits of the previous line. Starting with 1, you describe it as one 1, which becomes 11, then two 1s, which becomes 21, and so on.

Each term serves as a verbal explanation of the one that came before it. It may look like random chaos, but this sequence is a staple of recreational mathematics. Intriguingly, no matter what number you start with, the sequence always evolves in a predictable, stable way. It is a brilliant demonstration of how simple rules can create complex, self-referential patterns.
