Step-by-step explanation:
4/8 are red. If you simplify that you get 1/2.
From the recursive rule

it follows that


and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with

so that the explicit rule for the n-th term in the sequence is

Answer: (0,1) and (1.5,0)
