Induction puzzles

Induction puzzles are special kinds of puzzles that use a process called induction. With induction, you look at a bunch of examples and then figure out a rule from them. For instance, you may look at a bunch of different shapes, like circles and triangles, and then figure out that all of the shapes have something in common, like having three sides. After figuring out the rule, you use that rule to figure out answers for the puzzle.
