"Does 852655 appear in A005132 ?" is an open question in "A Handbook of Integer Sequences" Fifty Years Later by N. J. A. Sloane. https://arxiv.org/abs/2301.03149
Recamán's sequence in OEIS : https://oeis.org/A005132
852655 is the smallest number not present in the terms of the sequence that have been computed so far.
Market resolves YES if we manage either to compute A005132 terms and find 852655 before 2030.
Market resolves also to YES if the conjecture that every number eventually appears in Recamán's sequence is proven before 2030, even if we don't know 852655 exact position.
Market resolves to NO if there is a proof that 852655 does not appear in the sequence.
As I'm not patient enough to wait forever, if the 01/01/2030 this number is still not found or proven to be in the sequence, market will resolve also to NO.
