This research is a descriptive qualitative research that aims to describe students' creative thinking in solving arithmetic sequence problems in terms of self-efficacy. This research was conducted at SMK Kesehatan Dhermajaya. The subjects of this study were 3 grade XI students who were taken according to the aspects of self-efficacy, namely magnitude, strength, generality. Creative thinking indicators in this study are fluency, flexibility, and novelty. The results of this study indicate that the magnitude subject in the fluency aspect is that students can provide 2 possible jars needed. The flexibility aspect is that students can solve with 2 alternative solutions with the arithmetic sequence formula, and write an arithmetic sequence that is at odds with 2 and if added together the result is 90. The strength of the fluency aspect is that students provide 2 possible jars needed. At the same time, the aspects of flexibility and novelty have not been fulfilled. The subject of generality in the fluency aspect is that students can provide 3 possible jars. The flexibility aspect is that students can provide 2 different alternative solutions, namely using the arithmetic sequence formula and writing an arithmetic sequence that is 2 apart and then adding them up. The three subjects, still have not shown the uniqueness of the answer or used different strategies so that the novelty aspect has not been fulfilled.
