ANSWER:Step 1 of 18
Richardson Extrapolation and the Composite Trapezoidal Rule are combined in Romberg Integration. This indicates that in order to determine where the two arrows are pointing, we must first determine where they are coming from. The final diagonal term in the array is always the most precise estimate of the integral.
