 OFFSET 0,1 LINKS Index entries for linear recurrences with constant coefficients, signature (0,1). FORMULA a(n) = (1/2)*[45+43*(-1)^n]-22*[C(2*n,n) mod 2], with n>=0. - Paolo P. Lava, May 13 2009 From Colin Barker, Nov 10 2014: (Start) a(n) = (45+43*(-1)^n)/2 for n>0. a(n) = a(n-2) for n>2. G.f.: -(22*x^2+x+22) / ((x-1)*(x+1)).
