Apologies but i cant seem to work this one out.

Would it be possible top send me through the answer with a bit of detailed description?

I feel like I'm nearly there but cant crack it

operators.swift 
var results: [Int] = []
var index = 0
for n in 1...100 {
    // Enter your code below
    if (n / 7) && (n / 2) {
    results.insert(n, at: index)
    index += 1}
    // End code 
}

First, there is no need to create a new variable named index in order to append to the results array. This is an answer that satisfies the requirements. Often there is more than one way to pass a challenge. If you have any questions about the details of my answer below and would like me to explain it in more detail, please let me know. If not, I encourage you to try and find a different solution to the challenge that still satisfies the requirements to make sure you understand the concepts.

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if n%2==1 && n%7==0 {  // check If the number is both an odd number and a multiple of 7(using the % operator)
        results.append(n)
    }
    // End code 
}

Thank you very much for the promt reply. I had forgotten about the results.append function. I will have a play around later and see if i can solve this another way.
