EXAMPLE

a(3) = 97: y = x^2+15x+97.

If x = 0; y = 0+0+97 = 97, which is prime.

If x = 1; y = 1+15+97 = 113, which is prime.

If x = 2; y = 4+30+97 = 131, which is prime.

If x = 3; y = 9+45+97 = 151, which is prime.

If x = 4; y = 16+60+97 = 173, which is prime.

If x = 5; y = 25+75+97 = 197, which is prime.

If x = 6; y = 36+90+97 = 223, which is prime.

If x = 7; y = 49+105+97 = 251, which is prime.

If x = 8; y = 64+120+97 = 281, which is prime.
