# Find caluclation to equal this value?

How can I find the calculation needed to reach the given value? This is related to programming but I don't see how I can do this myself.

A = 1535683044
B = 1583000036
C = 155934150


What equation could be used with A and B to result in C?

Edit: Is this even possible?

• Try $C=\frac{A+B}{2}$. Pretty close. – André Nicolas Feb 11 '15 at 22:19
• @AndréNicolas that works! – ThatGuy343 Feb 11 '15 at 22:20
• @AndréNicolas im trying this against all the other values, this seems to be the relation. mind making your comment an answer so i can accept it? – ThatGuy343 Feb 11 '15 at 22:24
• Not quite. When we do the operation, at the end we get $170$ not $150$. Maybe there is a typo in one of your numbers. But at least we get an excellent approximation. – André Nicolas Feb 11 '15 at 22:24
• OK, will do that, to get it off the unanswered list. – André Nicolas Feb 11 '15 at 22:26

You will find that $C$ is very close to $\frac{A+B}{20}$.
Remark: Perhaps it is intended that $C$ be exactly $\frac{A+B}{20}$, or $\frac{A+B}{2}$. If so, there is a typo somewhere.
• We cannot find $A$ and $B$ if all we know is $C$. – André Nicolas Feb 11 '15 at 22:32
