Which feature allows you to automatically fill a sequence of numbers or dates in Excel?

The Fill Handle is a powerful feature in Excel that allows users to automatically generate a sequence of numbers or dates by simply dragging the small square found in the bottom-right corner of an active cell. When you use the Fill Handle, if the selected cell contains a number or date, dragging it down or across will continue the sequence based on the pattern established in the initial cell.

For example, if you start with the number 1 in a cell and drag the Fill Handle down, Excel will increment the values in each subsequent cell (1, 2, 3, etc.). Similarly, if you start with a date, dragging the Fill Handle will fill the cells with the following dates, effectively creating a series.

This feature enhances efficiency in data entry, minimizing the repetitive task of manually typing each number or date in a sequence. While other options may also relate to filling data in Excel, the Fill Handle specifically addresses the functionality of automatically extending a series based on an initial value through a simple drag-and-drop action.
