Answer:
class Foo:

Explanation:
This should cover part a to this question. The thing I'm not sure on is they use the term "method" which in python technically means a class function...but then list one argument with the function call which makes me think it is possibly just supposed to be a regular function. Which would be the following snippet. It would depend on if you are using classes or not yet in your coding class.
def F(n):
if n == 1:
return 1
return F(n - 1) + 3 * n - 2
Play around with it and look into python "lists" and "for loops" for part c. Part b I'm not sure what kind of example they want since I'm not in that class. Good luck!
