Working with logical operators: using remainder operator to calculate even numbers

Task: "If the number is both an odd number and a multiple of 7, append the value to the results array provided"

My code that won't pass:

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

for n in 1...100 {

     if n % 2 == 0 && n % 7 == 0 {
      results.append(n)
    }
}

x % 2 == 0 is even, not odd. if the result is 1, that's odd. it means there was a remainder of 1, which is true of all odd numbers when divided by 2.
