Geometric Progression: It is the sequence or series of numbers such that each number is obtained by multiplying or dividing the previous number with a constant number.The constant number is called the common ratio of the series. A sequence of numbers each one of which is equal to the preceding one multiplied by a number $q\ne0$ (the denominator of the progression). In mathematics, a geometric progression (sequence) (also inaccurately known as a geometric series) is a sequence of numbers such that the quotient of any two successive members of the sequence is a constant called the common ratio of the sequence. A geometric progression is a sequence in which each term (after the first) is determined by multiplying the preceding term by a constant. If the common ratio module is greater than 1, progression shows the exponential . To learn more about Arithmetic Progressio. Find the two possible values of the common ratio. As the numbers near zero, they become insignificantly small, allowing a sum to be calculated despite the series being infinite. See: Geometric Sequence. sum Sn . Initialize sum variable as 0.
