Given two Numbers, Finding Relation to third I'm trying to find the relation of three numbers. I know that two numbers have a relation that equate to the third. The tricky part is that they don't have to equal the third number exactly,but should be very close ($\pm 5$).
The data I've collected so far is 
341 = 11, 31
357 = 10, 157
383 = 9, 242
525 = 7, 57
501 = 7, 146
365 = 10, 100

These have to do with computer programming so I figured adding/multiplying one of the numbers by $256$ might be involved, but I cannot figure it out.  Is there a way to figure out the relationship of numbers like this?

This sound's a lot like linear algebra. I am assuming that you want an approximate function f(x,y) = z(where x,y are the first numbers and z is the thired). If you where looking for the connection between tow numbers you would do something like assuming f is polynomial of whatever degree. To force your situation to work with the one dimensional problem you can do as physicists do and guess the "wight" of x and y. so for instance you might assume the third number is a polynomial of xy, or of (x+y) or (x^7*y-5x) or (x +6) etc. each assumption will give you a relatively nice equation that will work for your points. 
That is what i would try any way's, good luck!.
