when n = 2‚ n 2 − n + 41 = 43 is prime‚ and so on. Even if one continues the experiment until n = 10‚ or even n = 20‚ one would not be able to find a counter-example. However‚ it is easy to see that the statement is wrong‚ for when n = 41 the expression is equal to 412 which definitely is not prime. While experimental evidence is insufficient to guarantee the truthfulness of a statement‚ it is often not possible to verify the statement for all possible cases either. For instance‚ one might
