This study aimed at designing learning trajectory (LT) for teaching Sequence and Series using Realistic Mathematics Education (RME) approach to improve the students' problem solving ability. The LT designed in this research covered real problems that helped students follow the math learning process to build their knowledge in solving mathematical problems. The LT was developed through a design research that consisted of a cyclic process of preparing the experiment, conducting the experiment, and retrospective analysis. The research's subject was 34 grade nine students at a junior high school in Nias Selatan, Indonesia. The data were collected through observation, interviews, checklist, videotaping, and analyzing the students' works. The results showed that the LT for teaching Sequence and Series using RME approach reached the criteria of validity and practicality. The LT also could help students build their own knowledge through problem solving activities to discover sequence and series concepts. © 2018 Institute of Physics Publishing. All rights reserved.
