Hi,

You can use the modulo calculation to establish if a number is a multiple of another number. The operator for this is % and the result of a modulo calculation will be 0 if it's a multiple (divides perfectly) or > 0 if it's not ( division has a remainder.

The code should look like this:

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if n%7 == 0 {
        print("\(n) is odd and multiple of 7") // Added just for effect
        results.append(n)
    }
    // End code
}
