All the methods in this test take an argument of the type Numbers. This is a class that has only one method you need to use: nextNumber which takes no arguments and returns a random number. The methods you will write will use the Numbers object as a source of numbers that the methods will then do things with like summing them up or averaging them, etc. Note that nextNumber returns a different random number each time you call it so if you need to use the same number more than once, you’ll need to save it in a variable.
