I understand how to get odd values by using (n % 2 != 0) but..?

Can you explain how you would get odd values by using % operator and 3?

For context - this is the hint on the question - "Hint: To check for an odd number you can either use the remainder operator and 3, or use the not operator to check for 'not even'"

logicalOperators.swift 
for n in 1...100 {
    // Enter your code below
    if (n % 7 == 0) && (n % 2 != 0){

        results.append(n)
    }
        // End code
}
