In Maths, Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio. This progression is also known as a geometric sequence of numbers that follow a pattern. Also, learn arithmetic progression … See more A geometric progression or a geometric sequence is the sequence, in which each term is varied by another by a common ratio. The next term of the sequence is … See more Some of the important properties of GP are listed below: 1. Three non-zero terms a, b, c are in GP if and only if b2= ac 2. In a GP,Three consecutive terms can be … See more Let a be the first term and r be the common ratio for a Geometric Sequence. Then, the second term, a2= a × r = ar Third term, a3 = a2 × r = ar × r = ar2 Similarly, … See more Consider the sequence a, ar, ar2, ar3,…… First term = a Second term = ar Third term = ar2 Similarly, nth term, tn = arn-1 Thus, the common ratio of geometric … See more
WebA geometric progression (GP) can be written as a, ar, ar 2, ar 3, … ar n – 1 in the case of a finite GP and a, ar, ar 2,…,ar n – 1 … in case of an infinite GP. We can calculate the sum to n terms of GP for finite and infinite GP using some formulas. Also, it is possible to derive the formula to find the sum of finite and finite GP separately.
