How do I get point between two high dimensional points?

I have two points in high dimensional space (e.g., 10 dimensions).

How can I get the point that is between these two points? I.e., if I were to imagine a line between the two original points, how do I find the coordinates of the middle of that line?

0.5*(x1+x2)

or in general:

(1-lambda)*x1 + lambda*x2

for 0<=lambda<=1.
