Logical operators

Hello, i've got stuck on this exercise, I think I got it logically right, but I've dont know what the syntax should be, can anyone help me out? Thank you!

The exercise requires to add to an array numbers that are odd and that divide by 7

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

for n in 1...100 {
    // Enter your code below
    if n / 7 == int && n / 2 != int {

    results.append(\n)

    }

    // End code 
}

You have a few things wrong with your logic.

Dividing an integer by an integer always results in an integer when working in Swift, so checking to see if n / 7 is an integer wouldn't work. Instead, you should try using the mod operator to check if n has a remainder when divided by 7, and if n has a remainder when divided by 2.

Also, you need to remove the "\" when appending n to results.

    if n % 7 == 0 && n % 2 != 0 {

    results.append(n)

    }

I hope this helps!
