Fundamental concepts involved in NCERT sequence and series:

 

  • A sequence is formed when numbers are placed in a specified order according to some criteria. A sequence may alternatively be described as a function with a set of natural numbers as its domain or a subset of natural numbers of types as its domain.

 

  • When a series has a finite number of terms, it is called a finite sequence, and when a sequence has an infinite number of terms, it is called an endless sequence. If it is the sequence, it is stated as a series. If the series has a finite number of terms, it is referred to as a finite series.

 

  • An arithmetic progression is a sequence in which the succeeding terms grow or decrease by the same constant (A.P.). In the A.P series, this constant is known as the common difference. In general, the first, common difference, and final terms in the A.P series are indicated by a, d and a+(n-1)*d respectively. 

 

  • A geometric progression, or G.P., is a sequence in which the ratio between each term and its previous term remains constant throughout the series. In the G.P series, this constant term is known as the common ratio. In general, the first term and its common ratio are indicated by a and r in the G.P series.

 

This article also illustrates the benefits of NCERT Mathematics textbooks:

 

  • It provides a variety of practice challenges: You will not be successful no matter how much time and effort you put into learning a topic unless and until you put that same effort into practice. NCERT textbooks have questions at the end of each chapter that are answered. In order to attain the best potential performance on the board examinations, students should practise a wide range of questions. In addition to these practise questions, it is recommended that you practise the NCERT Exemplar problems. As a consequence, you will be able to deal with even the most difficult problems with relative ease.

 

  • Assists students in comprehending concepts: All NCERT books are written by experts after conducting significant study on each topic in order to provide students with accurate and trustworthy information.

  • If an idea is well explained, no learner will find it difficult. It's only that the explanation method should be adapted to their unique learning needs. NCERT Solutions for CBSE Board Exams provide detailed explanations of each chapter, subject, and formula, allowing students to concentrate on their study. Because the ideas serve as a foundation for future job opportunities, Math for Classes 11 requires a full explanation.
