The Most Likely Common Difference of Arithmetic Progressions Among Primes

Abstract

Let $d^*_k(x)$ be the most likely common differences of arithmetic progressions of length $k+1$ among primes $\le x$. Based on the truth of Hardy–Littlewood Conjecture, we obtain that $\lim \limits _{x\rightarrow +\infty }d^*_k(x)=+\infty $ uniformly in k, and every prime divides all sufficiently large most likely common differences.
