What's the Rule

Input Output
0 1
1 3
2 7
3 11
4 15

What's the rule?
o 5
1 13
2 21
3 29
4 37

For the first one, the rule is 4x-1.

Plug the input into "x" and then check to see if you got the output right. Hope I helped!

Try 4 for the firt one

Input output
1 3+4
2 7+4
3 11+4
4 15+4
5 19+4
And 8 for the other...
Input output
0 5+8
1 13+8
2 21+8
3 29+8
4 37+8
5 45+8

Thanks Brooke!

You're welcome!

Thanks Kerry J but I did not understand it being 8, please explain. Thanks

Also, for the second one the rule is 8x+5.

I think that is what Kerry J was referring to.

To figure out the rule, let's analyze the pattern between the input and output values:

For the first set of values:
- When the input is 0, the output is 1.
- When the input is 1, the output is 3.
- When the input is 2, the output is 7.
- When the input is 3, the output is 11.
- When the input is 4, the output is 15.

From these values, we can see that the output is increasing by 2 between each input. Therefore, the rule for the first set of values is: output = (input * 2) + 1.

Applying this rule to the second set of values:
- When the input is 0, the expected output would be (0 * 2) + 1 = 1. Since the given output is 5, it does not follow the same rule.

Similarly, for the second set of values:
- When the input is 1, the expected output would be (1 * 2) + 1 = 3. The given output of 13 does not follow the same rule.
- When the input is 2, the expected output would be (2 * 2) + 1 = 5. The given output of 21 does not follow the same rule.

Based on the provided values, it is not possible to determine a single consistent rule that applies to all the input/output pairs.
