%N 5-Ramanujan primes; the interval (x/2,x] has at least n 4-Ramanujan primes for x >= a(n) but not for x = a(n)-1.
%C It is conjectured that primepi(a(n)) < 50*n for large n. - T. D. Noe, Aug 26 2011
%C The sequence is only conjectural without a proof of an upper bound on a(n) (like the bound A104272(n) < prime(3*n) proved by Laishram and used in computing Ramanujan primes). - Jonathan Sondow, Aug 27 2011
%C Subsequence of the 4-Ramanujan primes A192822, by the minimality of a(n). - _Jonathan Sondow_, Aug 21 2012
%Y Cf. A104272 (Ramanujan primes), A192820, A192821, A192822 (4-Ramanujan primes), A192824.
