... (Of course this could have been done more efficiently!) In all cases, there are at least 4 elements x with the same value of π(x). Source: Putnam 1995 B1. 7. The Fibonacci numbers are defined by the recurrence f0 = 0, f1 = 1 and fn = fn−1 + fn−2 for n ≥ 2. Show that the Fibonacci sequence is periodi ...

... whence ak − 1 | ar − 1. But ar − 1 < ak − 1, and thus ar − 1 = 0 — that is, r = 0. 16. Prove that if a > 3 then a, a + 2, and a + 4 cannot all be primes. Can they all be powers of primes? Suppose a is prime. If a ÷ 3 leaves a remainder of 1 then a + 2 is a multiple of 3. If a ÷ 3 leaves a remainder ...

... 5. If possible, give an example of a relation R on S = {a, b, c} with exactly 3 elements that is both symmetric and transitive but not reflexive. If it’s not possible, explain why not. This is not possible. Since it can’t be reflexive and must have three pairs then there must be a pair in which the ...
