Algebra Questions and Answers

A Geometric progression is a kind of order that includes an organized and immeasurable assortment of real numbers, wherein every term is acquired by multiplying its previous term through a constant value. Application of Geometric Progression is in physics, engineering, biology, economics, computer science, queueing theory, and finance that’s why Geometric Progression Questions and Answers is important to know. Geometric Progression Questions are in the form a, ar, ar², ar³ and so on.
The First term is denoted as = a
The common ratio is denoted as = r
