An input-output table has inputs 1, 2, 3, 4 and outputs 4, 8, 12, 16. What is the rule?
Please select an answer first.
Correct answer: A
The correct answer is Multiply the input by 4.
- Read the pattern: Compare consecutive terms or input-output pairs to find what changes each time.
- Apply the rule: Each output is 4 times its input: 1 × 4 = 4, 2 × 4 = 8, and so on.
- Check the choice: The correct choice is Multiply the input by 4.
Each output is 4 times its input: 1 × 4 = 4, 2 × 4 = 8, and so on.
