Autofill a column with increasing numbers

Excel allows one to automatically increment numbers in a column. For example, one can enter the number 1 in the first cell, and then drag downwards to increment from 1 to whatever number you'd like to end with. It saves you having to manually enter cell numbers as you go downwards. I can't find this function in Numbers for Mac. I have a workaround by creating a formula in the cell after the number 1. The formula is quite simply add 1 to the cell containing 1. Copy the formula and paste downwards. Excel made this really easy however and is there any equivalent in Numbers for Mac.
