I can write the recursion version correctly need help with writing a do loop in DrScheme.

After the do loop the variable x is sent to car L intially and then is updated to first element of everything but first element in list.

(define (sumiteration L)
  (do ((x (car L) (car(cdr L))))
    ((null? L))
    (set! sum (+ sum x)))
)
