a way to copy/paste formula every 7th column that increments formula reference by 1

I'm stumped figuring out a way to copy a formula from column I and paste into every 7th column thereafter (P, W, AF etc) but only have the reference cell increment the source column by 1. The formula returns a number from another sheet in cell S75 through BR75. I need S75 returned into I, T75 into W, U75 into AF, etc. Any suggestions?

formula right now in I8 ='Press 1'!S75
I need a way to copy/paste so that P8 ='Press 1'T75
W8 ='Press 1'!U75
