Giovanni Resta, Table of n, a(n) for n = 1..50
FORMULA
a(n) = Min_{j| floor(p(j)/j) = n}. Note that neither p(j)/j nor floor(p(j)/j) is monotonic.
a(n) = pi(A062743(n)).
EXAMPLE
The q(j)=p(j)/j quotient when the value 14 first appears: {j=251706, p(j)=3523841, q(j)=13.9998291} {251707, 3523901, 14.0000119} {251708, 3523903, 13.9999642} {251709, 3523921, 13.9999801} {251710, 3523957, 14.0000675} {251711, 3523963, 14.0000357}
PROG
(PARI) {a062742(m)=local(n, j); for(n=1, m, j=1; while(floor(prime(j)/j)!=n, j++); print1(j, ", "))} a062742(10^7)
