The two-day moving average is calculated by adding the demand for the current day and the previous day, and then dividing by 2. For example, the two-day moving average for day 10 is (15 + 13) / 2 = 14. The two-day moving average for day 11 is (14 + 12) / 2 = 13. Therefore, the forecast sales for the next day is 13.
