Models can be used to help generate and analyze patterns by showing a visual picture and image of the problem, which can make the problem easier to solve. For example, if the question was to find the surface area of a triangular prism, you could draw out a picture of a net to solve it easier. So, in conclusion, you can use models to analyze and generate patterns in order to easily and clearly solve the problem.
I don't know if this answer is entirely correct, but I hope this helps!!
