This is also possible with Simpson's method. Two approximations with n and 2n intervals give a new and improved estimate.
Take a look a this thread in the HP41 software library.


I have implemented a variant of the Romberg method that uses Simpson's rule to start with instead of teh Trapezoidal rule. You can find this variant method on my web site.
