Well, it's a right Riemann sum. So we're using the value of the function right over there, right at two plus five over n. So this value right over here, this is the natural log, the natural log of two plus five over n. And since this is the first rectangle, times one. Times one. And we could keep going. This one right over here, the width is the same, five over n. But what's the height? Well, the height here, this height right over here is gonna be the natural log of two plus five over n times two. Times two.
