Hello ppl. I am kinda newb. Have a question that I dont know how to search. I am creating some spreadsheet in libre calc. Now I want to add sum of (e2:e7) next column (g2:g7) and so on every 2 columns… How can I write it in a formula like ((e+2)2:(e+2)7) ? So it repeat itself every second column E, G, I, K and so on?

So I get in 1 column sum of the every second column in other page. I know how it works if i do it one by one… but I have there more than 50 columns.
