    In a personalized math learning system, students advance through progressively complex pattern recognition challenges where each level corresponds to a specific mathematical sequence. Given a student's current achievement level n, determine the mathematical pattern value they need to master before advancing to the next learning objective, where each value follows the star number sequence pattern.
