My next clue is to expand the original riddle by giving you more of the sequence. Reread the other clues if you like, it may help you.

The following is a sequence that is based on this topic. What is the next number in this sequence?

421
2
488
504
421
113
421
113
3933
3375
4154
4000
1216
4000
4000
4219
4000
4219
4000
?

Sorry if this is a stupid sequence and the answer ends up making you groan, but I thought of it so I figured I'd give it a try.

The below is a number puzzle. It should be read left to right, top to bottom.

Question 1 What is the next two rows of numbers.
Question 2 How was this reached.

1 1
2 1
1 2 1 1
1 1 1 2 2 1
? ? ? ? ? ?


An alternate solution:

Given that the first three are starting conditions, then the fourth line could be: 21111211

Explanation:
* The last two digits alternate between 11 and 21
* The first two digits, in the first three sequences repeat
* Interior numbers are shifted right

Hence the next number would be: 1221111221

Ta da!

Ano, this is a rather old puzzle, and I've seen it several times in books, school newspapers, and on the internet....

If you use comparrs idea, then you could switch around number order, so the finished result is never the same.
