Ray Chandler, Table of n, a(n) for n = 0..652
Index entries for linear recurrences with constant coefficients, signature (35,-35,1).
FORMULA
a(n) = 2*A046176(n+1)+1, e.g., 2379 = 2*1189 + 1.
G.f.: (x^2+34*x-3) / ((x-1)*(x^2-34*x+1)). - Colin Barker, Dec 14 2014 [adjusted for corrected term and empirical g.f. confirmed for more terms and recurrence of source sequences. - Ray Chandler, Feb 05 2024]
EXAMPLE
a(1) = 71 = 3*5 + 3*7 + 5*7.
