These two separate sequences use the same rule. This gives them the potential to extend much further. Still, I think they are longer than half the similar sequences based on this rule.




2, 1, 8, 5, 2, 5, 8, 6, 7, 9, 7, 7, 0







3, 1, 5, 3, 9, 2, 4, 3, 9, 7, 3, 1, 0




They are purely mathematical, no other subject is applied. What are they based on?

    @Brandon_J, it's a different track, and one which can be easily followed.

    The two given sequences stop at the 13th term. Other examples, with the same simple rule, can be infinite.
