### Geometric Progression

Geometric Progression Definition Geometric Progression is the sequence of numbers such that the next term of the sequence comes by multiplying or dividing the preceding number with the constant (non-zero) number. And the constant number is called the Common Ratio. It is also known as the Geometric Sequence. a, ar, ar2, ar3,……..,arn The first term […]

### Arithmetic Progression

Arithmetic Progression Definition Arithmetic Progression is the sequence of numbers such that the difference between the two successive terms is always constant. The difference is called the common difference. It is also known as Arithmetic Sequence. The first term of the sequence is called the initial term which is denoted as ‘a’. The difference by which […]

### Special sequences

Special sequences 1. Square numbers 2. Cube numbers 3. Triangular numbers 4. Fibonacci numbers Square numbers A square number is the product of multiplying a whole number by itself. Square numbers can be represented using dots arranged to make squares. The general formula of sequences: $displaystyle {{T}_{n}}={{n}^{2}}$ Square numbers form the (infinite) sequence: 1,4,9,16,25,36,……….. Square numbers may be […]

### Sequences

Sequences A sequence is a collection of objects in which repetition is allowed and order matters. What is a sequence number? Number sequence is a progression of an ordered list of numbers governed by a pattern or rule. Types of sequences Infinite sequence is a sequence that continues indefinitely without terminating.
