This study reports an analysis of inductive reasoning of Mexican middle school mathematics teachers, when solving tasks of generalization of a quadratic sequence in the context of figural patterns. Data was collected from individual interviews and written answers to generalization tasks. Based on Cañadas and Castro's inductive reasoning model, we found that most of the teachers followed four stages to obtain a general rule: observation of particular cases, search of patterns, conjecture formulation and generalization.
