The following two related sequences are determined in only slightly different ways:

1. 1
   11
   100
   121
   221
   1100
   1211
   2101
   

2. 1
   10
   21
   100
   121
   210
   301
   1000
   

What the next few terms of each, and how are they determined?

Series are n^2 to base 3 and 4 respectively.
Next in series are 9^2:
to base 3 = 10000
to base 4 = 1101
