WebWe can add up the first four terms in the sequence 2n+1: 4 Σ n=1 (2n+1) = 3 + 5 + 7 + 9 = 24 We can use other letters, here we use i and sum up i × (i+1), going from 1 to 3: 3 Σ i=1 i (i+1) = 1×2 + 2×3 + 3×4 = 20 And we can start and end with any number. Here we go from 3 to 5: 5 Σ i=3 i i + 1 = 3 4 + 4 5 + 5 6 Webis solved. Otherwise, by the pigeonhole principle, there are at least m + 1 values of n i that are equal. Then, the integers a i corresponding to these n i cannot divide each other. Useful Facts • Bertrand’s Postulate. For every positive integer n, there exists a prime p such that n ≤ p ≤ 2n. • Gauss’s Lemma.
