Does lim_{n->oo} a(n+1)/a(n) exist? If so, is the limit Pi? - Ryan Propper, Sep 15 2005

Robert G. Wilson v, Table of n, a(n) for n = 0..36 (terms 1..36 from Chai Wah Wu).
EXAMPLE
a(3) = 17 as 17*prime(17) = 17*59 = 1003 > 10^3.
MAPLE
for n from 0 to 11 do b:=proc(k) if k*ithprime(k)>10^n then k else fi end: a[n]:=[seq(b(k), k=1..100000)][1]: od: seq(a[n], n=0..11); # Emeric Deutsch, Aug 04 2005
MATHEMATICA
n = 0; For[k = 1, k > 0, k++, If[k*Prime[k] > 10^n, Print[k]; n++ ]] (* Ryan Propper, Sep 15 2005 and modified by Robert G. Wilson v, Feb 25 2019 to reflect the offset of 0 *)
