All known terms of this sequence satisfy the relation 2.4*a(n) - 12 < a(n+1) < 2.7*a(n) + 1 is true.
a(n) is the largest number m such that floor(prime(m)/m)=n-1. - Farideh Firoozbakht, Sep 13 2005

EXAMPLE
3140421934 = pi(24*3140421934) and 3140421934 is the largest number with this property, so a(24) = 3140421934.
