The second rectangle, the two still applies. This two is the width of the rectangle. But now we want to multiply it times f of three, not f of two. So this f of n isn't going to, this f of n isn't going to, isn't going to pass muster. And so let's see, let's see how we want to think about it. So when n is, so when n is one, two, three, four, we're gonna take f of, so f of n, or I should say f of n, we're gonna take f of something. So here, this first one, we're gonna take f of one.
