Palindromic sequences (Posted on 2005-10-31)

1,1
1,2,1
1,3,2,3,1
1,4,3,2,3,4,1
1,5,4,3,5,2,5,3,4,5,1
1,6,5,4,3,5,2,5,3,4,5,6,1

What are the next several lines and how are they formed?

Do the sequences have any special feature?

Does the pattern continue indefinitely?

No worries, mate. I understand what you were trying to say. At the same time, I am as impressed as ever that GoFish and Tristan took what my simplistic sequence, and discovered it was a "subset" of an "official" sequence. I'm glad the options were open for creative and elegant solutions to the puzzle.
