What is the out put for:

Input Output
4 0
5 2
6 4
7 6
12 ?
explain the rule please

To determine the output for the given input values, there must be a rule or pattern that relates the input to the output. By examining the given input-output pairs, we can try to identify the pattern.

Looking at the pairs, we notice that the output values are increasing by 2 for each subsequent input value. From this observation, we can derive a rule or formula.

The rule or formula can be expressed as follows:

Output = (Input - 4) * 2

Let's apply this rule to the input values provided in the question:

For input 4:
Output = (4 - 4) * 2 = 0

For input 5:
Output = (5 - 4) * 2 = 2

For input 6:
Output = (6 - 4) * 2 = 4

For input 7:
Output = (7 - 4) * 2 = 6

Using this pattern, we can continue to find the output for input 12:

For input 12:
Output = (12 - 4) * 2 = 8

Therefore, the output for input 12 is 8.

The general rule is to subtract 4 from the input value and then multiply the result by 2 to obtain the corresponding output.
