When you substitute all the numbers from 1 to 100 into the following formula by Euler, how many numbers result in giving Prime Numbers? Here is Euler's formula: x^2 - x + 41. Any help would be great. Thank you. Is it: 25, 37, 68, 86?
41, 42, 45, 50, 57, 66, 77, 82, 83, 85, 88, 90, 92, 97 give non-primes = 14
So
100 - 14 = 86
