And this makes sense. Every time we increase n by one, we are adding another three, which is consistent with what we saw there. We start at two when n equals zero. This is just, that three n is just zero, so you start at two, and then you keep, every time you increase n by one, you are just adding three again. So finally, when n is equal to three, two plus three times three is two plus, or is 11, I should say. And so this also is exactly the same sum. So I feel good about both of these.
