Geometric Progression Geometric Progression (GP) is a sequence, in which next term in the sequence is obtained by multiplying the previous term by a fixed number, and the fixed number is called the Common Ratio. Example : 5,15,45,135 … is a GP with first term 5 and common difference 3 General form of Geometric Progression A geometric sequence or a progression is one in which the ratio between two consecutive terms is constant. This ratio is known as the common ratio denoted by ‘r’, where r ≠ 0. The elements of the sequence be denoted by: a, ar, ar 2 , ar 3 , … , ar n-1 common ratio ‘r’= successive term/preceding term =a 2 /a 1 = a 3 /a 2 = = a n /a n-1 Types of Geometric Progression Geometric progression can be classified as Finite Geometric Progression (Finite GP) Infinite Geometric Progression (Infinite GP) Finite G.P. is a sequence that contains finite t...
