# Not sure what they're asking me to do here...

They didn't really teach me how to compute this from the lesson I feel like can someone help?

loops.swift
```let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

while counter < 6 {
print("Terminate")
counter += 1
sum += counter
}
```

hi aj picard! A couple things. If you want to add up each index of the "numbers" array, you would have to go through each index and add them together. That's actually what the counter is for. Having "counter" start at 0, you're going to use that as your index for your "numbers" array. So, by saying numbers[counter], and then increasing that counter by 1 each time, you're essentially saying: numbers[0], numbers [1], numbers[2], etc. Now, you're going to want to store these numbers in a placeholder variable called newValue:

```var newValue = numbers [counter]
```

then you want to add this to your "sum" variable like this:

```sum += newValue
```

then of course you need to up your counter:

```counter += 1
```

so your completed code should like this:

```let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

while counter < numbers.count {
var newValue = numbers[counter]
sum += newValue
counter += 1
}
```
