Question: Exponential smoothing: F_(t+1) = alpha * A_t + (1-alpha) * F_t The sale of American flags shows strong seasonality by month. I run a regression

Exponential smoothing: F_(t+1) = alpha * A_t + (1-alpha) * F_t The sale of American flags shows strong seasonality by month. I run a regression on the data and find the trend estimate to be Y = 100 + 217*t, where t=1 corresponds to Jan 2020. Each month is a period, and the seasonal relative for every month except for July and November is 1. In July and November, the seasonal relatives are 3 and 2 respectively. How many more flags do I expect to sell in July 2023 than Feb
