Shaoxiong Yuan, Generalized Identities of Certain Continued Fractions, arXiv:1907.12459 [math.NT], 2019. Index entries for linear recurrences with constant coefficients, signature (199,1). FORMULA G.f.: x/(1 - 199*x - x^2). a(n) = 199*a(n-1) + a(n-2) for n>1, a(0)=0, a(1)=1. a(n) = A167398(n)/89. For n >= 1, a(n) equals the denominator of the continued fraction [199, 199, ..., 199] (with n copies of 199). The numerator of that continued fraction is a(n+1). - Greg Dresden and Shaoxiong Yuan, Jul 29 2019 MATHEMATICA Fibonacci[11 Range[0, 20]]/89 PROG (MAGMA) [Fibonacci(11*n)/89: n in [0..30]]; (PARI) a(n) = fibonacci(11*n)/89 \\ Felix FrÃ¶hlich, Jul 30 2019 CROSSREFS Cf.
