When n is an integer, is the value of formula n ^ 2 + N + 11 necessarily prime?
Why? The specific analysis process

When n is an integer, is the value of formula n ^ 2 + N + 11 a prime number? A: not necessarily! When n = 1,2,3,. 9, the value of formula n ^ 2 + N + 11: 13,17,23,..., 101 is a prime number. When n = 10, the value of formula n ^ 2 + N + 11 = 121 = 11 * 11 is not a prime number
