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?

10000 for 1st 1101 for the 2nd series
Both are squares of consecutive integers 1 to 8; first in ternary second in 4-base system
