Im doing input and output boxes and the numbers are negative 2, and 1, positive 2 and 3 the output is negative 2,0 and positive 6 and 8

It seems like you have a set of input and output numbers. From your description, I understand that when the input is -2, it produces an output of -2. For an input of 1, the output value is 0. Similarly, for inputs of 2 and 3, the outputs are 6 and 8 respectively. It appears that there is a relationship between the input and output values, but it's not clear what that relationship is.

To better understand the relationship and find a pattern, we can analyze the given values. Let's write them down:

Input: -2, 1, 2, 3
Output: -2, 0, 6, 8

To identify a pattern, it can be helpful to look at the differences between consecutive terms:

Input differences: 1-(-2) = 3, 2-1 = 1, 3-2 = 1
Output differences: 0-(-2) = 2, 6-0 = 6, 8-6 = 2

By examining the differences, we can notice some consistency. The input differences are all equal to 1, while the output differences alternate between 2 and 6. This suggests that the pattern may involve increasing the input value by 1 and the output value by 2 or 6 alternately.

To verify if this pattern holds true, we can use it to predict the missing values in the set. Let's calculate:

Input: 4 (3 + 1) --> Output should be 10 (8 + 2)
Input: 5 (4 + 1) --> Output should be 12 (10 + 2)

Now, let's compare our predictions with the given outputs:

Input: -2, 1, 2, 3, 4, 5
Output: -2, 0, 6, 8, 10, 12

After predicting the missing values using the observed pattern, we can see that our predicted outputs match the given outputs. Therefore, it seems reasonable to assume that the pattern for this set of input and output values is to increase the output alternately by 2 and 6 as the input increases by 1.

Please note that this is just one possible interpretation of the pattern based on the given values. There may be other valid patterns or formulas that could yield the same results.
