// Enter your code below while sum < todo.count { print( todo[sum]) sum++ }
let numbers = [2,8,1,16,4,3,9]

Treehouse TeacherIt's simply asking you to take all the numbers in the array and add them together. And it wants it implemented in a while loop. My code looked like this:
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while(counter < numbers.count){
sum += numbers[counter]
counter++
}
So while the counter is less than the number of items in the array, we take the number at the position of counter starting at 0. So on the first iteration we add 2 to sum. The second iteration counter is 1 and we add the array element at index position 1 to sum. This gives us 2 plus 8 (10) as our new sum. We continue down the line until the array runs out.
Hope this helps!

10,723 PointsUse counter variable as a counter and add value to sum:
let numbers = [2,8,1,16,4,3,9] var sum = 0 var counter = 0
// Enter your code below while(counter < numbers.count){ sum += numbers[counter] counter++ }
