Moving Average Solution
MA3(5) = (1/5)(4 + 5 + 7 + 6 + 8) = 30/5 = 6.0
MA4(5) = (1/5)(5 + 7 + 6 + 8 + 9) = 35/5 = 7.0
MA5(5) = (1/5)(7 + 6 + 8 + 9 + 5) = 35/5 = 7.0
MA6(5) = (1/5)(6 + 8 + 9 + 5 + 2) = 30/5 = 6.0
MA7(5) = (1/5)(8 + 9 + 5 + 2 + 3.5) = 27.5/5 = 5.5
MA8(5) = (1/5)(9 + 5 + 2 + 3.5 + 5.5) = 25/5 = 5.0
MA9(5) = (1/5)(5 + 2 + 3.5 + 5.5 + 6.5) = 22.5/5 = 4.5
