%N A089781 Successive coprime numbers with distinct successive differences: (a(k+1),
               a(k))= (a(m+1),a(m)) = 1 and a(k+1)-a(k) = a(m+1)-a(m) <==> m=k.
%C A089781 Conjecture: If a(k+1)-a(k) = n then k < C*n. Can some one find an estimate 
               for the constant C?
%e A089781 5 follows 2 as 4 is not coprime to 2 and 5-2 = 3, 2-1 =1.
