The correct answer is "add 1".
Please Note:
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 1 to each input number:
3 + 1 = 4
5 + 1 = 6
7 + 1 = 8
6 + 1 = 7
On adding 1 to the input numbers, we get the corresponding output numbers.
So, the rule is "add 1”.
