A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
If I understand correctly and you want figures in Column I that are the Column H figure plus 4 you can use this.
=H2+4
Fill this down next to all of the figures in Column H.
If there are blank cells mixed in that don't need to be added, you can use this instead. The formula can then be filled into rows that don't have a number yet.
=IF(H2>0,H2+4,"")
