Hey there,

you have to write a if with the condition that n is odd - you can check if the remainder of n divided by 2 is not zero with the modulo operator, if that's the case it's odd - and n is a multiple of 7 which you can check by comparing the remainder of n divided by 7 and 0.

If both conditions evaluate to true you should append the current value of n to the results array. You can do that by using the append method on the results array.

A working solution could look like this:

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if n % 2 != 0 && n % 7 == 0 {
      results.append(n)
    }
    // End code 
}

I hope that helps! :)
