Hey Jomar Martinez,

Always post some code even if you know what you're posting is wrong and horrible! I'll help you with this one this time though. The challenge asks us:

Challenge Task 1 of 1:

var results: [Int] = []

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

// The for loop iterates over the range of numbers 1...100 and assigns each to the constant n
// We then need to create an if statement and perform two checks (operations) on the constant n
 // The first check is if the number is odd (n % 2 != 0)
     // If the remainder of n divided by 2 is not equal to 0, the number must be odd
// the second check is if the number is a multiple of 7 (n % 7 == 0)
    // If the remainder of n divided by 7 is equal to 0, the number must be a multiple of 7
// We use the AND operator && to specify that BOTH of these conditions must be true

    if (n % 2 != 0) && (n % 7 == 0) {
     // If both are true, we use the append() method to add the value of n to the results array
        results.append(n)

    }
    // End code 
}

Good Luck!
