Create a repeat-while loop increases growingValue by the square of its current value each time thru

Create a repeat-while loop that increases growingValue by the square of its current value each time through the loop as long as the result is less than 100. var growingValue = 2

So I think this is what they are looking for.

var growingValue = 2
var result = 0

while growingValue * growingValue < 100 {
    result = growingValue * growingValue
    growingValue = growingValue + result
}

or this also does it:

var growingValue = 2

while growingValue * growingValue < 100 {
    growingValue = growingValue * growingValue + growingValue
}

Unless by result it means after adding the square back to itself:

var growingValue = 2

while growingValue * growingValue + growingValue < 100 {
    growingValue = growingValue * growingValue + growingValue
}

The second and third versions are more concise so I would say one of those. Looks like it runs through the exact same number of time for both 2 and 3. They worded this one kind of tricky didn't they. Where are you getting these from, Tree House?

I added the specific repeat term to the body in my code below I think showing how the repeat is what was asking for.

I think all 4 are best answers

Also you can post your code blocks as below

```Swift
    //Code goes here
```    //Then 3 back ticks like this below

var growingValue = 2 var size = 100

repeat { print(growingValue) growingValue = growingValue * 2 } while growingValue < 100
