%N A113728 a(n) is the integer between p(n) and p(n+2) which is divisible by (p(n+2)-p(n)), 
               where p(n) is the n-th prime.
%C A113728 Exactly one integer exists between each p(n+2) and p(n) which is divisible 
               by (p(n+2)-p(n)).

%e A113728 Between the primes 19 and 29 is the composite 20 and 20 is divisible 
               by (29-19)=10. So 20 is in the sequence.
