Limit[a(n)/10^n,n->Infinity] = Log[10, 3 ]
= 0.477121254719662437295027903...
since the real root possessing the smallest absolute value
of expression (1-2*x-3*x^2) (found in the g.f.) equals 1/3.

Limit[a(n)/10^n,n->Infinity] = Log[10, 3+2*sqrt(2) ]
= 0.765551370675726156638799048...
since the real root possessing the smallest absolute value
of expression (1-6*x+x^2) (found in the g.f.) equals 1/(3+2*sqrt(2)).
