%N A110613 a(n+3) = 5*a(n+2) - 2*a(n+1) - 8*a(n), a(0) = 1, a(1) = 0, a(2) = 3.
%C A110613 A Jacobsthal related sequence (A001045). This sequence was calculated 
               using the same rules given for A108618; the "initial seed" is the 
               floretion given in the program code, below.
%F A110613 G.f. (1-5*x+5*x^2)/((4*x-1)*(2*x-1)*(x+1)); Program "Superseeker" finds: 
               a(n) + a(n+1) = A007582(n) = A007581(n+1) - A007581(n); a(n+2) - 
               a(n) = A049775(n); a(n) + 2*a(n+1) + a(n+2) = A087440(n+1);
