Problem with odd/ multiple of 7 question

Aye, I can't seem to find out what's wrong with my code here, can someone take a look? The editor is telling me to check my logical operators but it works in swift playground.

logicalOperators.swift 
var results: [Int] = []

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

Hi there! You are so close. In fact, you're only off by one single character. You've typed this:

!(n & 2 == 0)

But we want to use the modulus operator here, just as you did to find out if n is evenly divisible by 7.

!(n % 2 == 0)

This says if the number is not evenly divisible by 2 (odd).

Hope this helps! :sparkles:
