The formula used to calculate the Reverse Average (V1) is:
\[ V1 = 2 \cdot AV - V2 \]
Where:
The Reverse Average is a method used to calculate an initial value from an average. By multiplying the average by 2 and then subtracting the final or second value, you can determine the missing number value.
Let's assume the average (AV) is 10 and the known value (V2) is 6.
Using the formula:
\[ V1 = 2 \cdot 10 - 6 = 20 - 6 = 14 \]
Therefore, the missing value (V1) is 14.
