Welcome to Lecture 11 of the Permutation & Combination series on AAPKE SARTHI with VKS Sir 🚀

In this lecture, we explore one of the most interesting techniques in factorial-based problems — the Telescopic or Cancel-Out Pattern.
This concept helps simplify complex factorial expressions and is extremely useful in IIT JEE and competitive exams.

📘 In This Lecture You’ll Learn:
✅ Concept of factorial telescoping (cancel-out pattern)
✅ Tricks to simplify large factorial ratios
✅ How to identify telescopic patterns in P&C problems
✅ Step-by-step approach for JEE-level questions
✅ Practice problems for Class 11, 12 & competitive exams

This session strengthens your factorial foundation — an essential part of Permutation & Combination and JEE Maths.
