Linear Growth and Population Modeling

This video tutorial covers the concept of linear growth, focusing on expressing it in both recursive and explicit forms. The lesson explains how to find the common difference, which is crucial for determining the growth rate. An example involving the Javelina population is used to illustrate these concepts, including calculating the common difference and predicting future population sizes. The tutorial also includes a graphical representation of the data and concludes with deriving the necessary equations for modeling linear growth.

How is the recursive formula for linear growth expressed?

• P_sub_N = P_sub_N + 1 - D

• P_sub_N = P_sub_0 - D x N

• P_sub_N = P_sub_0 + D x N

• P_sub_N = P_sub_N - 1 + D
