The image shows a pyramid structure with three boxes: one on top and two below. The top box contains the number 6, while the bottom-left box contains the number -2, and the bottom-right box is currently empty.

If this image represents a number puzzle, where the top number is typically the sum of the two numbers below, we can determine the missing value by solving for the unknown number.

Let the unknown number in the bottom-right box be represented by $x$.

We are given the relationship: $-2 + x = 6$

Solving for $x$: $x = 6 - (-2)$ $x = 6 + 2 = 8$

Thus, the missing number in the bottom-right box is 8.

Do you want more details, or do you have any questions?

Here are some related questions:

1. How would the equation change if the top number were different?
2. What if the sum is based on multiplication instead of addition?
3. How could this structure be used in algebraic expressions?
4. Can you think of an alternate method to verify the solution?
5. What happens if the negative number is on the right instead of the left?

Tip: Always verify the relationships between numbers in puzzles by checking operations like addition or subtraction carefully!
