Abstract
This study was purposed to describe problems used to measure mathematical thinking aspect reasoning for senior high school students in topic sequences and series.The indicators used to measure mathematical thinking aspect reasoning are inductive, deductive, and logical analysis.This is design research consisting: preliminary design, focus group discussions, trials, observation and interview, and retrospective analysis.The subjects of this study were 3 senior high school students from grade 11 who were taken randomly.There are three problem-solving questions used in this study. The data analysis used qualitative technique.As the result of this study, for questions number 1 and 3, all three students were able to do deductively and logic analysis and make conclusions correctly. the three students can do deductively and logic analysis in question number 2, only students 3 in solving the correct questions and conclusions, while students 1 and 2 are less precise in their conclusions. for inductive reasoning indicators have not yet emerged from the three students.
