## Sierpinski Triangle

Sierpinski Triangle also called as Sierpiński Gasket or Sierpiński Sieve is a fractal with a shape of an equilateral triangle. It is subdivided recursively into smaller equilateral triangles. This triangle …

## Pascal’s Triangle

Pascal’s Triangle is one of the interesting number patterns in mathematics. This is a triangular array constructed by summing adjacent elements in preceding rows. History  Pascal’s triangle is named after …

## Harmonic Progression

In mathematics, a harmonic progression(H.P.) is a progression formed by taking the reciprocals of an arithmetic progression. The sequence is a harmonic progression when each term is the harmonic mean …

## Geometric Progression

A Geometric Progression(G.P.) is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number or a constant ratio(r). E.g. 2, 4, …

## Arithmetic Progression

In mathematics, an Arithmetic Progression(AP) or Arithmetic Sequence is a sequence of numbers such that the difference between the consecutive terms is constant and is known as common difference. For …
