Explanation
The Forecast Sheet provides options that affect how the forecast is generated.
Important Options
Forecast End
Determines how far into the future Excel predicts.
Confidence Interval
Controls the confidence range displayed around the forecast.
Seasonality
Represents repeating patterns in the historical data.
For example:

- Lower sales every January

Excel can automatically detect seasonality, or you can specify it when appropriate.
Practice
Use monthly sales data containing seasonal variations and compare the forecast with automatic seasonality.
