Write a function called sequence_ab which takes 3 input parameters a, b and N and returns a Python list [x0, x1,...,xN] of length N + 1 representing the recursive sequence 1, x 1 1, Xn+2 = axn+1 + bxn For example, if a = b = 1 and N = 5 then the function returns the partial Fibonacci sequence [1,1,2,3,5,8]. [ ]: # YOUR CODE HERE = []: "Check function returns correct datatype. (1 mark)" assert type (sequence_ab (1,1,5)) == list "Return value should be a list." print("Problem 2 Test 1: Success!")
