Using the loop construct, add the current value of number to the numbers array. Inside of the loop, add 1 to the number variable. If the numbers array has more than 3 items, use the break keyword to exit the loop.

loop.rb 
numbers = []

number = 0

numbers.push(number)
loop do
  number = number + 1

  if numbers > 3
    break
  end

end

# write your loop here

First: You should be pushing number into the numbers array inside of the loop. You have to push the value onto the end during every iteration.

Second, you should be looking for the numbers array to contain more than 3 items, not the number variable to be greater than 3. You would accomplish this with numbers.count > 3 or numbers.length > 3. They're the same thing.

My code looks like the following. I had to use == instead of > because of the order of events:

numbers = []

number = 0

number += 1

loop do
     numbers.push(number)

 if  numbers.count == 3
     break 
end

end

If you decide to do your push after the if statement, you'll have to change from == to >
