12-67.

For many years mathematicians tried to come up with a formula to generate prime numbers. One candidate was the expression *n*^{2} + *n* + 41, where *n* is a positive integer. Try at least 3 or 4 numbers. What do you think of the formula? Does it work? Could you prove it?

Try 1, 2, 3 and 4. Does it work?

Try 41. Does it work?
