1. What does a Sequence and a Series Mean?

The sequence is an arrangement of numbers in definite order following a rule. It can also be defined as a function whose domain is a set of natural numbers or subsets of the type. A finite sequence is a sequence that contains a finite number of terms. And a sequence is infinite if it is not a finite sequence. If a1,a2,a3,.... is a sequence, then the sum of a1+a2+a3+... is called a series. It is a finite series if it has a finite number of terms.

2. What are Some of the Common Types of Sequences?

Some common sequences are:

Arithmetic Progression (A.P)- it is a sequence in which the terms increase and decrease by the same constant, which is known as the common difference of the A.P. The first term of an A.P is usually denoted by ‘a’, the common difference is denoted by ‘d’ and the last term is denoted by ‘l’.

Geometric Progression (G.P)-it is a sequence where the ratio of any term to its preceding term is the same throughout. The first term of the G.P is denoted by ‘a’ and the common ratio by ‘r’.
