A snow shovel company forecasts demand that shows strong seasonality by quarter. The linear trend can be estimated by the equation y(t) = 1000 + 1000t. The forecasts start with t = 0, which corresponds with Q1 of 2021 (Jan - Mar). t = 1 corresponds to Q2 of 2021 (Apr - Jun) and so on. The seasonal relatives for Q1 = 1.5, Q2 = 0.5, Q3 = 1, Q4 = 2. What is the seasonalized forecast for Q2 of 2022.
