Hint: To check for an odd number you can use the remainder operator and 3

I wonder why the lesson suggest using n % 3 to check for odd numbers, doesn't it make more sense to use n % 2?

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

for n in 1...100 {
    if n % 7 == 0 && n % 2 == 1 {
        results.append(n)
    }
}

You're correct - using n % 2 would make more sense. It's probably a typo in the challenge.
