1. Problem Description

The problem presents a pyramid where each number in a brick is the sum of the two numbers in the bricks directly below it. We are given the values -3 and 2 in the bottom bricks, and we need to find the value of the brick above them, which is currently marked with a question mark.

2. Solution Steps

To find the value of the top brick, we simply add the numbers in the two bricks below it.
Value=−3+2Value = -3 + 2
Value=−1Value = -1

3. Final Answer

The number that should replace the question mark is -1.
