The concepts which are given in the solution of NCERT Maths Class 11 Chapter 9 are listed below: <\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-size: 12pt;\"><span style=\"font-weight: 400;\">When the numbers are arranged in a specific order by following some rule then it is known as a sequence. A sequence can also be defined as such function having a set of natural numbers as domain or subset of natural numbers of types <\/span><span style=\"font-weight: 400;\">When the sequence is having finite numbers of terms then it is known as a finite sequence and when the sequence is having an infinite number of terms then it is known as infinite terms. <\/span><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-size: 12pt;\"><span style=\"font-weight: 400;\">If <\/span><span style=\"font-weight: 400;\">is the sequence, then the series is expressed <\/span><span style=\"font-weight: 400;\">And if the series has a finite number of terms then it is known as a finite series.<\/span><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-size: 12pt;\"><span style=\"font-weight: 400;\">Such a sequence in which its consecutive terms increase or decrease by the same constant is known as an arithmetic progression (A.P.).

And this constant term is known as the common ratio in the G.P series. Generally in the G.P series, the first term and its common ratio are denoted by a and r respectively.

P.), Arithmetic Mean (A.M.), Geometric Progression (G.P.), Geometric Mean (G.M), infinite G.P. Algon with these students are also able to find the general term in a G.P and A.P series., the sum of n terms of a G.P. and A.P series, and the sum of infinite G.P and A.P  and also the relation between A.M. and G.M.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span><span style=\"font-size: 12pt;\"><b>Frequently Asked Questions<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\t\t<section class=\"sc_fs_faq sc_card \">\n\t\t\t<div>\n\t\t\t\t<h5><span class=\"ez-toc-section\" id=\"What_is_the_concept_of_Arithmetic_Progression_discussed_in_Chapter_9_of_NCERT_Exemplar_Solutions_for_Class_11_Maths\"><\/span>What is the concept of Arithmetic Progression discussed in Chapter 9 of NCERT Exemplar Solutions for Class 11 Maths?<span class=\"ez-toc-section-end\"><\/span><\/h5>\t\t\t\t<div>\n\t\t\t\t\t\t\t\t\t\t<p>\n\t\t\t\t\t\tSuch a sequence in which there are specific patterns among the consecutive terms is known as Progression.
