im lost can some one give me a clue

For this challenge, we'd like to know in a range of values from 1 to 100, how many numbers are both odd, and a multiple of 7.

To start us off, I've written a for loop to iterate over the desired range of values and named the local constant n. Your job is to write an if statement inside the for loop to carry out the desired checks.

If the number is indeed both an odd number and a multiple of 7, append the value to the results array provided.

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 
var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if !n even || %3 print("results.append")
    // End code 
}

Try this code:

var results: [Int] = []

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