Erdős Problem #250 has been PROVED (Erdős's conjecture holds). Statement: Is $$ \sum_{n=1}^\infty \frac{\sigma(n)}{2^n} $$ irrational? Here $\sigma(n)$ is the sum of divisors function. The answer is yes, as shown by Nesterenko [Ne96]. [Ne96] Nesterenko, Yu V., _Modular functions and transcendence questions_, Mat. Sb. 187 *9* (1996), 1319--1348. Topics: number theory, irrationality. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: A066766.
