%N A092850 Number of primes between A092800(n) and 10^n.
%F A092850 a(n) = PrimePi(10^n)-PrimePi(A092800(n)) = PrimePi(10^n)-PrimePi(A046731(n)/
               A006880(n)). - Robert G. Wilson v (rgwv(AT)rgwv.com), Jan 19 2007
%e A092850 Below 10^1 there are 4 primes: 2+3+5+7=17. The rounded mean is 17/4 =~ 
               4. There are 2 primes > 4: 5 and 7, so a(1)=2.
