Write a recursive function my seq(n) in Python called that returns an, the n th term in the recursively-defined sequence given as follows: an = 3an1 + 28an2, a0 = 1 a1 = 5 In addition, please solve the recursive equation using the characteristic roots method and write down an explicit formula for an inside a comment at the bottom. You only have to write down the explicit formula, you dont have to show your work.
