How do you write a multiple of 7 in code?

I dont know how to design a code that only takes n for a multiple of 7. Thanks.

operators.swift 
var results: [Int] = [7,14,21,28,35,42,49,56,63,70,77,84,91,98]

for n in 1...100 {
    // Enter your code below
    if n !even && n=results {
    print("results")
    }
    // End code 
}

Hi Adrian -

You need to do two checks with your IF statement in both cases you will use the modulus operator. In the first check you are checking if n is a multiple of 7 and then if it is an odd number. After you have done so you need to append the those numbers to results. There is no need to manually type the numbers in as you have done

var results: [Int] = []

for n in 1...100 {
    // Enter your code below

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

    results.append(n)

    }

    // End code 
}
