Almost!

  1. Use == when you check n%7.
  2. You don't need to increment n if the condition is not satisfied. The for loop automatically increments n for you.
var results: [Int] = []

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