EXAMPLE
a(4) = 5 because, for (p, q) = (67, 5), 2*4+1 = 9 = 2*67 - 5^3 = 134 - 125 = 9.
MAPLE
for n from 3 by 2 to 200 do:jj:=0:for j from 1 to 50000 while (jj=0) do:q:=ithprime(j):p:=(q^3+n)/2:if type(p, prime)=true then jj:=1: printf(`%d, `, q):else fi:od:if jj=0 then printf(`%d, `, 0):else fi:od:
