EXAMPLE
|
a(2) = 83: y = x^2+13x+83.
If x = 0; y = 0+0+83 = 83, which is prime.
If x = 1; y = 1+13+83 = 97, which is prime.
If x = 2; y = 4+26+83 = 113, which is prime.
If x = 3; y = 9+39+83 = 131, which is prime.
If x = 4; y = 16+52+83 = 151, which is prime.
If x = 5; y = 25+65+83 = 173, which is prime.
If x = 6; y = 36+78+83 = 197, which is prime.
If x = 7; y = 49+91+83 = 223, which is prime.
