CBSE Class 10 Maths Chapter 5 Important Questions: Many things follow a certain pattern around us, in nature and in our daily lives, such as the holes of a honeycomb, the spirals on a pine cone, etc. While in some we might observe that the succeeding terms are obtained by adding a fixed number, in others we get it by multiplying with a fixed number, whereas in another we might find that they are squares of consecutive numbers, and so on.
Chapter 5 Arithmetic Progression discusses the patterns where succeeding terms are obtained by adding a fixed number to the preceding terms and explores how to find their nth terms and the sum of n consecutive terms to help students use this knowledge in solving some daily life problems.
In this article, we have covered all the important questions from CBSE Class 10 Mathematics Chapter 5 Arithmetic Progression along with the solutions.
