-
B
Subtract 4
The correct answer is "Subtract 4".
Please Note:
Subtraction is the operation that decreases a number by taking away from it.
Solution:
To find the correct rule, we consider the given table.
We observe that the given rule makes each number decrease. This implies subtraction.
We try subtracting 4 from each input number:
9 - 4 = 5
6 - 4 = 2
10 - 4 = 6
11 - 4 = 7
On subtracting 4 from the input numbers, we get the corresponding output numbers.
So, the rule is “subtract 4”.
