I recommend that you use an Excel Spreadsheet.

Enter 9 into cell A1

Enter = =2*A1 - 4 into A2

Use Excel's clipboard to copy the formula in A2 and paste it into cells A3 through A5.

You will observe the following numbers in cells A1 through A5:

9
14
24
44
84

If you want more terms, copy and paste the formula into more cells.
