basically, if the x values (and corresponding y values) are in increasing order (from left to right), you multiply the interval length (difference in x values) by the right functional value (the y value at the right end of the interval) and sum over all intervals.

Your function is already arranged in increasing order, so your first interval is between x = 5 and x = 6.

What is the length of that interval?
What is the height (y value) at the right endpoint?

What is their product?

That is the first number in your Right Riemann Sum.
