Increase Row reference when using Index

Hi I have an order form that uses index for find a title and then needs to show all the values below a given title E.G Quantity. I can get it to work but I was wondering if there is an easy way to increase the row reference.

So I have =INDEX('Paste Area'!F:F,(MATCH($A$8,'Paste Area'!F:F,0)+2)) I want it so when I drag the formula down the +2 will become +3 then +4 and so on.

Thanks for any help.
