Doddy -- I think the bottom row of y_correct in problem 4 (x = 7) is incorrect.
I have checked again and they are correct. By the way, the test cases have been checked by MathWorks before I can publish the problem. If you already get a generic formula for the previous cases, it should work for x=7 as well. Hint: There are two other mathematical constants involved in the solution.
I think when x=7,the y(7,1)is 62 not 61
