Answer:The "Fill handle" is used to fill a series of data in a column or row in Microsoft Excel. It is represented by a small black square located in the lower-right corner of the active cell.
To use the Fill handle to fill a series of data, you can do the following:
Type the starting value in the active cell.
Move the cursor to the Fill handle until it changes to a black cross.
Click and hold the left mouse button and drag the Fill handle to the desired number of cells to be filled.
Release the mouse button to fill the selected cells with the series of data.
For example, if you type "1" in the first cell and drag the Fill handle down two cells, Excel will automatically fill the cells with "2" and "3". Similarly, if you type "Monday" in the first cell and drag the Fill handle across three cells, Excel will fill the cells with "Tuesday", "Wednesday", and "Thursday".
