Abstract
Geometric sequences and series is one of mathematical content for middle and high school in Indonesia. This research aims to analyze students^ learning obstacles, specifically on geometric sequence and series. To do so, a written test consists of four questions related to conceptual understanding and the applications of geometric sequences and series was administered to 20 students from one senior high schools in Kota Tangerang Selatan. After being tested, students^ answers were analyzed for possible learning obstacles. Four students were selected to conduct interviews based on their answers. The result shows that the learning obstacles are classified into epistemological, ontogenic, and didactical obstacles. Furthermore, the results of this study can be used by teachers as considerations in designing learning situation on the topic of sequence and series.
