Final answer:
The reasoning used in the example is inductive reasoning, where a generalization is made based on specific instances or patterns.
Step-by-step explanation:
The reasoning used in the given example is inductive reasoning. Inductive reasoning is a type of reasoning where you make generalizations based on specific instances or patterns. In this example, the observation that there is always a line of people outside the bakery leads to the conclusion that the bakery sells delicious treats. However, it is important to note that the conclusion is not guaranteed to be true, as it is based on an inference rather than deductive logic.
