A series representing a function of the form sz k 0bkz ak where a is the centre bk are the coefficients and bkz ak are the terms of the series. More specifically if the variable is x then all the terms of the series involve powers of x. In a geometric series every term has the same coefficient.
In a power series the coefficients may be different usually according to a rule thats specified in the sigma notation.
