Erdős Problem 1138. Let $x/2 < y < x$ and $C > 1$ . If $d = \max_{p_n < x}(p_{n+1} - p_n)$ , where $p_n$ denotes the $n$ -th prime, then is it true that $\pi(y + Cd) - \pi(y) \sim \frac{Cd}{\log y}$ ?

The proof uses `sorry`: part of the argument is written but not proved. Lean accepts the file; it does not accept the theorem.
