Inserting a series
You can copy cell values into other cells and, for example, increment them at the same time (the value is changed according to mathematical rules).
Example
To create a list, counting in fives from zero to one hundred, enter 0 in a cell. Drag the cell handle downwards to select 20 rows. Select
and select as the type. Set 5 as the Increment and 100 as the final value.
