Answer:
The missing values to complete the diagram are:
4 → 6
2 → 5
-1 → -3
To find the missing values, we need to follow the pattern of the given arrows.
Starting with 4 and going to 6, we add 2 to get to the next number. So, starting with 2, we add 3 to get the missing value of 5.
Going from 2 to 5, we add 3 once again. So, to get from 5 to the next number, we add 3 to get 8.
To find the missing value that goes from an unknown number to -3, we need to subtract 3. Since we have already used the numbers 2 and 4, we can try a negative number. Starting with -1 and subtracting 3 gives us the missing value of -3.
Therefore, the completed diagram would look like this:
4 → 6
2 → 5
-1 → -3
Another Method
Here's the completed diagram with the missing values filled in based on the pattern:
```
4 → 6
2 → 4
-1 → -3
```
The pattern seems to be that for each input value (x), the output value (y) is x + 2.
