Let s(n) denote the smallest prime divisor and d(n) denote the number of positive divisors of a positive integer n>1. Is it possible to choose 2023 positive integers a1,a2,...,a2023 with a1<a2−1<...<a2023−2022 such that for all k=1,...,2022 we have d(ak+1−ak−1)>2023k and s(ak+1−ak)>2023k?Proposed by Nikola Velov
