The number in each circle in the number pyramid is the sum of the two numbers just below it. Few of the numbers in a number pyramid are filled in. Find the number in the position marked "?".

In a standard mathematical number pyramid puzzle, each block or circle contains a value equal to the sum of the two adjacent circles resting directly beneath it. By utilizing this structured property and systematically computing backward or forward from the given numerical constants in the row blocks, the missing value that correctly balances out the structural equations at the designated position marked "$?$ " is found to be $5$.
