%N A085376 Ratio-dependent insertion sequence I(0.36704) (see the link below).
%C A085376 This sequence is the ratio-determined insertion sequence (RDIS) "twin" 
               of I(0.37802)=A080874 and "child" of I(0.33344)=A001835 and I(0.38208)=A001906 
               in the RDIS recurrence tree (see the link for an explanation of terms). 
               See A082630, A082981, A085348 and A085349 for recent examples of 
               RDIS sequences.

%F A085376 It is conjectured that a(n)=10a(n-2)-a(n-4).
%F A085376 Apparently a(n)a(n+3) = -3 + a(n+1)a(n+2). - R. Stephan, May 29 2004
