I do not know why you would need to do this, but if you need this often, consider a function inside .vimrc:

function! Nameme()
    1
    let mov = 1
    let start = 1
    let inc = 0
    while 1
        call append(line('.'), range(start, start+inc))
        let mov += 2
        let inc += 1
        let start += inc
        if mov + line('.') > line('$')
            break
        endif
        execute mov + line('.')
    endwhile
endfunction

Then you could just :call Nameme().

It is possible in Vim, merging another file containing the numbers to insert (created by /bin/cat -n for example), here is the beginning.

gg         go to first line
o1<esc>"ayy   a (will increase) initialized to 1
"byy        b (will be cumsum of a) initialized to 1
qz          loop this:
:.,<c-r>a   advance by a lines
"bp         put a(a-1)

... but I will only continue if you format your question so that it does not end up deleted
