# Another Next Number Question

This is a bit different number sequence. Format and punctuation are on purpose.

What are the blanks?

4
1 2 2

'1 2, 1 1 2 1 1 1 1 2 1 1 1:
1 2 1 1 3, _ _ _ _ _.


Hint 1:

Going down the rabbit hole may lead to a clue.

Also added the knowledge tag. The other odd tag is another hint.

• (Nice puzzle concept! A suggestion for future submissions: Without the hint, this probably wasn't solvable. Puzzles should be forward-solvable from information they contain, not desperate exercises in "guess what the setter was thinking", and should contain all the information needed to solve in the initial post. If vital information is added later in a "hint", that's not a hint, it's a fundamental part of the puzzle and needs to be there to start!) – Rubio Apr 1 '18 at 8:10
