The forecast value for November using a three-month moving average with weights of 5, 3, and 1 for the most current (October), next most current (September), and oldest value (August), respectively, is calculated as follows: $$\frac{(19 \times 5) + (17 \times 3) + (27 \times 1)}{5 + 3 + 1} = \frac{95 + 51 + 27}{9} = \frac{173}{9} = 19.22.$$
