%N Primes of form n^2 + 19n + 17.

%C 0<=n<=14 gives primes.

%e a(3) = 83 = 3^2 + 19*3 + 17 is in the sequence because it is prime. a(15)=527 is not because 527 = 17*31.

%p with(numtheory): for n from 0 to 300 do if isprime(n^2 + 19*n + 17) then printf(`%d,`,n^2 + 19*n + 17) fi; od:

%t Select[Table[n^2+19n+17,{n,0,60}],PrimeQ] (* _Harvey P. Dale_, Jun 21 2011 *)
