The population in this article is growing at a rate of 2, 4, 8, 16 and 32.

This type of growth is called exponential growth.

Exponential growth occurs when the whole number of new members added to an increase is proportional to those already present in the group.

#### This article is about the population growth rate.

It starts by introducing what it means to grow and then goes on to talk about different types of growth rates like linear, exponential and logistic.

#### This article also talks about how populations can be modelled with these equations .

So that they are limited in size or have an unlimited supply for humans to calculate their needs in a particular area.

The long-form content looks like this:

A population is growing at a rate of x, y, z which type of growth does this describe?

The whole number of new members added to an increase is proportional to those already present in the group.

Therefore, we say that there has been exponential growth (x*y=z).
