Creating a projections spreadsheet with quarterly totals in the columns

[yellow281]

I would like to calculate my revenue growth with a simple percentage of the prior months revenue (=C10*0.2+C10) across a 12 month basis. However, I calculate totals on a quarterly basis. I would like to have my formula skip my quarterly total columns.. in this case F, J, N so that I can drag my formula across 12 months and not have my quarterly totals effected. Is this possible and how?

Thanks!

Assuming you're starting point is column A (January) you would then have

A-Jan
B-Feb
C-Mar
D-Blank
E-April

To fill across, input your formula in B,C, and E, highlight these 4 cells, and drag across.
Once you're done with that you can tell me how you're acheiving 20% month over month growth
