Problem Statement

Positive real numbers a1,a2,,a2024a_1, a_2, \ldots, a_{2024} are arranged in a circle. It turned out that for any i=1,2,,2024i = 1, 2, \ldots, 2024, the following condition holds: aiai+1<ai+2a_ia_{i+1} < a_{i+2}. (Here we assume that a2025=a1a_{2025} = a_1 and a2026=a2a_{2026} = a_2). What largest number of positive integers could there be among these numbers a1,a2,,a2024a_1, a_2, \ldots, a_{2024}?
