Exercise 6.9 of Class 11 Mathematics (2025 New Book - Punjab Curriculum) focuses on harmonic progression (H.P.), harmonic mean (H.M.), and their relationship with arithmetic mean (A.M.) and geometric mean (G.M.). This exercise includes conceptual and proof-based questions, inserting harmonic means between two numbers, deriving identities, and solving inequalities such as H.M. ≤ G.M. ≤ A.M.. It is a crucial part of Chapter 6: Sequences and Series and builds a strong foundation for competitive exams and higher-level math.
