Find the rule from the table below:

• A

• B

Addition is the operation that increases a number by adding to it.

Solution:

To find the correct rule, we consider the given table.

We observe that the given rule makes each number increase. This implies addition.

We try adding 4 to each input number:

5 + 4 = 9
7 + 4 = 11
2 + 4 = 6
3 + 4 = 7

On adding 4 to the input numbers, we get the corresponding output numbers.

So, the rule is "add 4”.
