Hey Dharma,

When checking to see if n is a multiple of seven, you should use the modulo operator like you did when trying to find if n is even. This is because the modulo is used to find if a number is a multiple of another (evens are multiples of 2, odds aren't). Your code should 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 
}

Hope this helps, Rodrigo
