-
B
Subtract 2
The correct answer is "Subtract 1".
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 1 from each input number:
8 - 1 = 7
9 - 1 = 8
6 - 1 = 5
2 - 1 = 1
On subtracting 1 from the input numbers, we get the corresponding output numbers.
So, the rule is “subtract 1”.
