Here is a cool sequence.

1,10,101,1020,10301,______,_______...

What numbers go in the two blanks?

104020,1050301,10604020... so on, when the third number gets to 9, next cycle will start it from 1 again and the first number will be changed to 2 then goes the third cycle and so on... numbers between zeros are always 1 through 9. (Probably not that simple?)
