Answer 3

It seems like you're trying to demonstrate a pattern. If you want to continue this pattern:

400 + 400 = 800

Each time you add the same number to itself, you double the result. So, when you add 200 to 200, you get 400, and when you add 400 to 400, you get 800. This pattern continues, and you can keep doubling the result by adding the same number to itself.
