Online resources for practicing induction questions include the website Geometer, which offers two papers on induction problems, one introducing the concept and the other providing practice problems. Additionally, searching for past math olympiad papers can yield questions that can be solved using induction techniques. The Cut the Knot website features an article on induction with numerous examples, while the NRICH site also provides useful content, albeit with fewer examples. For more effective searches, using the term "mathematical induction" is recommended. These resources can significantly aid in improving induction problem-solving skills.
