Let {an be a sequence of real numbers. Then, an is absolutely con- verge if and only if an converge [1]. The Cauchy Convergence Criterion imply that every absolutely convergence series are convergence [2]. The goal of this study is to generalized the notion of absolute convergence by replacing the absolute value || by a nonnegative function f. Let fR [0, +∞) be a function. We say that an is f-converge if and only if f(an) converge. The goal of this study is to give a test that determine when the series is f-converge, similar to root test [3] and ratio test [4] in absolutely converge.
