  Any three basic hypergeometric series {}_{2}phi_{1} whose respective
parameters (a, b, c) differ by integer powers of the base q satisfy a linear
relation with coefficients which are rational functions of a, b, c, q and the
variable x. These relations are called three term relations for the basic
hypergeometric series {}_{2}phi_{1}. This paper gives explicit expressions for
the coefficients of these three term relations.
