Abstract This paper deals with a certain family of series which is derived from generating functions of the Frobenius-Euler and Apostol type polynomials and numbers. When special cases of this series are examined, it is shown that it generates some well-known families of zeta functions, such as the Hurwitz zeta and the Lerch zeta functions, etc. We also present an open problem for this relation. We provide an analytic continuation of this function. By using the Cauchy Residue Theorem, we show that this series interpolates the Frobenius-Euler type polynomials at negative integers. Moreover, by applying the Laplace transform to the generating function for these polynomials, we get infinite series representations involving the Lerch zeta function and these polynomials. In addition, we show that this interpolation function can be represented in terms of the Lerch zeta function and the Hurwitz zeta function. Some special values for the results are also given.
