**Calculating moving average forecast** I need to provide a step-by-step solution for the forecasting topic using the moving average. The demand data for months 1-6 is 150, 160, 170, 165, 175, 180. I want to calculate the 3-month moving average for month 7 using the last three months' data (months 4-6): 165, 175, and 180. Calculating the sum gives me 520, and dividing by 3 results in 173.33 units. I can round this as needed, possibly to 173 units.**Creating final answer for moving average** I think I should present the final answer as 173.33 units, noting that rounding is common to the nearest whole unit. It’s important to include a brief explanation of the moving average concept and to use a formula like MA3(t+1) = (D_t + D_{t-1} + D_{t-2})/3, where t refers to months 6, 5, and 4. I'll keep formatting light but include bullet points as necessary, since the user wants a step-by-step breakdown. Let’s finalize that!
