Year	1	2	3	4	5
Mileage	3,100	3,950	3,500	3,800	3,700.    Using a​ 2-year moving​ average, the forecast for year 6​ =

To calculate the 2-year moving average forecast for year 6, we take the average of the mileage values from years 4 and 5.

Here are the mileage values for years 4 and 5:
- Year 4: 3,800
- Year 5: 3,700

Now, we compute the average:
\[
\text{2-year moving average} = \frac{3,800 + 3,700}{2} = \frac{7,500}{2} = 3,750
\]

So, the forecast for year 6 using the 2-year moving average is **3,750 miles**.

1. How would the forecast change if we used a 3-year moving average?
2. What is the total mileage over the 5-year period?
3. How does the moving average method compare to other forecasting methods?
4. Can we use a weighted moving average for this dataset? If so, how?
5. How would adding more years of data affect the forecast?

**Tip:** Moving averages smooth out short-term fluctuations, making it easier to identify trends in the data.
