What is geometric progression - Definition and Meaning

Geometric Progression :

Geometric progression is otherwise called as Geometric sequence. It is sequence of number, where each number after the first one is found by multiplying each previous number by the fixed common ratio.

Formula :

In general, the progression is written as {a, ar, ar2, ar3, ar4... } here, a - first term, r - common ratio (that is factor between the terms) (or) The n-th term of a geometric sequence with initial value a and common ratio r is given by xn = ar(n-1)

Example :

1, 3, 9, 27, 81, 243.... Above is the geometric progression with the common ratio 3.
