 OFFSET 0,2 COMMENTS One of 10 linear second-order recurrence sequences satisfying (a(n)*a(n-1)-1) * (a(n)*a(n+1)-1) = (a(n)+1)^4 and together forming A350916. LINKS Index entries for linear recurrences with constant coefficients, signature (24,-24,1). FORMULA G.f.: (1 - 7*x + 2*x^2)/((1 - x)*(1 - 23*x + x^2)). - Stefano Spezia, Jan 22 2022 21*a(n) = 4+17*A097778(n)-38*A097778(n-1). - R. J.
