FORMULA

a(n)=F(n, 34), the n-th Fibonacci polynomial evaluated at x=34. - T. D. Noe (noe(AT)sspectra.com), Jan 19 2006

a(n)=34*a(n-1)+a(n-2), n>1 ; a(0)=1, a(1)=34 . G.f.: 1/(1-34*x-x^2). [From Philippe DELEHAM (kolotoko(AT)wanadoo.fr), Nov 23 2008]

a(n)=(1/2)*{[17+sqrt(290)]^n+[17-sqrt(290)]^n}+(17/580)*sqrt(290)*{[17+sqrt(290)]^n-[17-sqrt(290)]^n}, with n>=0 [From Paolo P. Lava (paoloplava(AT)gmail.com), Dec 12 2008]

MATHEMATICA

a=0; lst={}; s=0; Do[a=s-(a-1); AppendTo[lst, a]; s+=a*34, {n, 3*4!}]; lst [From Vladimir Orlovsky (4vladimir(AT)gmail.com), Oct 27 2009]
