Table of n, a(n) for n=1..15.

Index to sequences with linear recurrences with constant coefficients, signature (0,11,0,11,0,-1).

FORMULA

For n odd a(n) = 11a(n-2) + a(n-3), for n even a(n) = 11a(n-1)- a(n-3); with a(1,2) = 1 (For Fibonacci sequence: factor 2 instead of 11).

G.f.: x*(1+x+109*x^3-10*x^4)/((1+x^2)*(1-12*x^2+x^4)). [Colin Barker, Jul 27 2012]
