When we say that a collection of objects is listed in a sequence, we usually mean that the collection is ordered in such a way that has an identified first member, second member, third member, and so on. For example, population of human beings or bacteria at different times form a sequence. The amount of money deposited in a bank, over a number of years forms a sequence. Sequences have important applications in several spheres of human activities. You will learn about A. M, special series in forms of the sum to n terms of consecutive natural numbers, sum to n terms of squares of natural numbers, and sum to n terms of cubes of natural numbers, etc.

The formulae list covers all formulae which provides the students a simple way to study of revise the chapter. A sequence is an ordered collection of objects in which repetitions are allowed. There is a pattern in this sequence, the difference between any two consecutive numbers is 10, and thus this sequence is Progression. This type of progression is called Arithmetic Progression. A series is the sum of the terms of a sequence. By Login, you agree to our Terms and Privacy Policies.
