What are example of what's my rule table and state the rule?

A "What's My Rule" table is a tool used to identify patterns based on input-output pairs. For example, if the rule is "add 2," the table might show inputs of 1, 2, and 3 with corresponding outputs of 3, 4, and 5. Alternatively, if the rule is "multiply by 3," the inputs of 1, 2, and 3 would yield outputs of 3, 6, and 9. The goal is to discern the underlying rule based on observed relationships between the inputs and outputs.
