Question

Let n be a positive integer such that 12 + 13 + 17 + 1n is an integer. Which of the following statements is not true:

Accepted Answer

Since 12 + 13 + 17 = 4142, 0 < _n (4142 + 1n) < 4142 + 1n < 4142 + 11 < 2 From which it follows that 4142 + 1n = 1 and n = 42. The only answer choice that is not true is n > 84.
