Aproximation is convergence to a definite value by means of a repetative
algorithm. Averaging over a set of numbers consists of adding them up
and diving by the number of addends. Contrast finding the square root of
two by the Newton-Rapheson approximation to finding the average age of
persons living in Philadelphia on a given day. Different processes
entirely. One knows ab initio that the averge of a set of numbers is not
likely to be a number in that set.
