Series Extrapolation Problems

THE THREE-TERM series problems which have been discussed are to be solved by the integration of the given pieces of information, one with another. No extension or extrapolation of the series beyond its three terms is called for, nor would such extension be possible in any of the examples we have considered, since in none of them is there a rule or principle of serial relationship to be discovered. A type of problem that has been much used in intelligence tests, however, is one which provides a few terms of a series where some such principle is involved, and requires the subject to supply others, in either direction - or in both directions - from the terms given.
