Hi there,

I tested for "oddness" by asking if n % 2 != 0; then check if n % 7 == 0. If both are true, append the result. That looks like:

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.

Steve.

This is almost exactly what I did. I was moving so I didn't have internet to answer the question earlier. 

var results: [Int] = []

for n in 1...100 {
    if n % 2 != 0 && n % 7 == 0 {
        print("\(n) This is an odd number and a multiple of 7.")
        results.append(n)
    }
}

Awesome answer Steve!
