At first glance, the sequence grows very slowly because we are adding small fractions. However, as stays within a range , we are repeatedly adding

denotes the greatest integer function).

Unlike the shorter, high-speed AMC or AIME exams, the VMO often feels like a marathon. Problems are designed to test deep structural understanding rather than just "tricks." Vietnam has historically been a powerhouse in the International Mathematical Olympiad (IMO), and the VMO is the sieve that catches their finest analytical minds. Selected Problem: Sequences & Convergence Selected Problems of the Vietnamese Mathematica...

Proving bounds or convergence in sequences. At first glance, the sequence grows very slowly

. The beauty of the problem lies in proving that it doesn't "skip" over an integer due to the discrete steps. Why this matters Vietnamese problems frequently focus on: Problems are designed to test deep structural understanding

Deep dives into roots and coefficients that require more than just Vieta’s formulas.
