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?

Tristan, that´s not my intention with caps to "convey an angry tone", and I hope that Bob doesn´t think this.

I was trying only to "call the attention" for the text. I´m right now fixing my comment.

Sorry if I was misunderstood.
