It keeps asking me to check the numbers appended to the array - 7,21,35,49,63,77,91

what am i doing wrong?

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

for n in 1...100 {
    // Enter your code below
    if n * 7 < 100 && n % 2 != 0{
        results += [7,21,35,49,63,77,91]
    }

    // End code 
}

Hi Rob,

You don't have to hardcode the values that you are appending to the array. Use the append() to add the number as it iterates the for statement and passes the conditions of the if clause

var results: [Int] = []

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

    // End code 
}

var results: [Int] = []

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

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

    results.append(n)

    }

    // End code 
}
