Well was little bit a trick question ;) , sadly i forgotten most my math from high school

well then, you just use the slope formula and generate a linear function
m=(y2-y1)/(x2-x1)
insert that value into the slope intercept form of a linear equation (y=mx+b) along with one of the points and solve for b
b=y-mx
and then generate a generic function using the m and b you've found
y=mx+b
then just substitute in any x between the two points and you'll get the value for y

that take care of your question?

Between two numbers

are we talking interpolation between two points or interpolation of a function?
