ARITHMETIC PROGRESSION  This chapter introduces students to a new topic that is  Arithmetic Progression i.e A.P. Here, students will learn to represent a situation or problems in the form of A.P, finding the first term and difference of an A.P, finding out whether a series is A.P or not. The chapter goes on to explain how to find out the nth term of an AP by using the following formula; a n  = a + (n-1) d and also how to find sum of first n terms of an A.P using the two different formula : Sn= n/2{ 2a + (n — 1)d} Sn = n/2 { a + l} The chapter ends with higher-level questions based on AP to enhance students analytical and power solving skills.

Here ‘a’ is called coefficient of x, ‘b’ is called coefficients of y and c is called constant term. Eg. 6x + 2y + 5 = 0, 5x – 2y + 3 = 0 etc. Solution Of a Linear Equation Let ax + by + c = 0 be a given li...
