We would like to show you a description here but the site wont allow us. In this case the sum to be calculated despite the series comprising infinite terms. If the numbers are approaching zero they become insignificantly small.

Geometric progressions have many uses in todays society such as calculating interest on money in a bank account. In the case of the geometric series you just need to specify the first term a and the constant ratio r. If x a y is an arithmetic progression then a is called arithmetic meanIf x a y is a geometric progression then a is called geometric meanIf x a y form a harmonic progression then a is called harmonic mean. We will explain what this means in more simple terms later on and take a look at.
