The chapter “Sequences and Series” in NCERT Class 11 Maths introduces students to the study of ordered numbers and their sums. It covers arithmetic progression (AP), geometric progression (GP), and special series, along with formulas to calculate nth term and sum of n terms.
Key topics include properties of sequences, relationship between terms, sum of series using formulas, and solving real-life problems. The chapter also introduces arithmetic-geometric sequences and series, helping students build a foundation for advanced mathematics.
Through solved examples, step-by-step derivations, and exercises, students develop logical reasoning and analytical skills.
This chapter is essential for Class 11 board exams and competitive exams like JEE and NEET, as sequences and series form a critical part of algebra and problem-solving in mathematics.
