The NCERT Solutions for class 11 maths chapter 8 Sequences and series will help the students to gain an in-depth knowledge of the topics covered in the chapter. It explains the meaning of ‘Sequences’ and how they play an important role in various human activities. We encounter numerous examples of sequence events in our daily lives, such as the population of a country, the amount of money deposited in a bank, etc. When any collection is ordered in such a way that its members are identified as first, second, third, and so on, then that collection is said to be listed in the form of a ‘sequence’. 

These NCERT solutions for class 11 maths chapter 8 also talk about ‘progressions’, which are a type of sequence that follows a set of rules. These NCERT solutions are designed by highly qualified teachers at eSaral so that students can attempt difficult questions with complete confidence. With the help of NCERT solutions here, you can learn new ways to solve a specific problem in a short amount of time so that you can do better in the class 11 maths exam. These solutions have been developed based on in-depth analysis of each question and problem-solving techniques.

Important Topics covered in Chapter 8 - Sequences and Series

NCERT solutions of chapter 8 Sequences and series is one of the most significant chapters of class 11. From a rise in the number of people to a rise in the price of any given commodity over a certain period of time, we find sequences in our daily lives. Chapter 8 of class 11 will introduce students to many intricate concepts that fall under the category of ‘Sequence and Series’

8.1 Introduction

8.2 Sequences

8.3 Series

8.4 Geometric Progression

8.4.1 General term of a G.P

8.4.2 Sum to n terms of a G.P

8.4.3 Geometric Mean (G.M)

8.5 Relationship Between A.M and G.M

8.1 Introduction - In this chapter you will learn Sequences, Series, Geometric Progression and relation between A.M and G.M.

8.2 Sequences - In this section, you’ll learn about the different types of sequences, such as arithmetical sequences, geometric sequences, and harmonic sequences. You’ll also learn how to identify the n term of each kind of sequence.

8.3 Series - You will learn how to solve series-related problems.

8.4 Geometric Progression
             8.4.1 General term of a G.P
             8.4.2 Sum to n terms of a G.P
