Formula:
The formula to find the missing number (X) in a set, given the desired average (Avg) and other known numbers (n1, n2, ..., nk), is:
X = (Avg × Total Count) - Sum of Known Numbers
Where:
- Avg: The target average for the complete set of numbers.
- Total Count: The total number of items expected in the set, including the single missing number.
- Sum of Known Numbers: The sum of all numbers you already have in the set.
