%N A069203 a(1)=0 a(2)=3 a(n+2)=(a(n+1)+a(n))/3 if (a(n+1)+a(n)==0 (mod 3)); a(n+2)=a(n+1)+a(n) 
               otherwise.
%C A069203 A Collatz-Fibonacci mixture. If a(1)=0 and a(2)=m not congruent to 3, 
               a(n) is cyclic (m,m,2m). Does this sequence diverge to infinity if 
               a(1)=0 and a(2)=m == 0 (mod 3)?
