A124124 %F & %C

[zak seidov]

Neil, John, seqfans,

Both John's formulas are OK,
and they may be right down as a single one
(though requiring more "seeds"):

%F A124124 
With given a(1..6), a(i)=7*(a(i-2)-a(i-4))+a(i-6)

Also, %C may be added: 

%C A124124 For 2n^2-2n-3 (with minus at 2nd term),
a(n) = 1 + A124124(n) - Zak Seidov Dec 04 2006.

%I A124124 
%S A124124

%C A124124 For 2n^2-2n-3 (with minus at 2nd term),
a(n) = 1 + A124124(n) - Zak Seidov Dec 04 2006. 
%F A124124 With given a(1..6), a(i)=7*(a(i-2)-a(i-4))
+a(i-6)- Zak Seidov Dec 04 2006
