Why does dividing the final(chosen) height in a line by 2 give you the average height(y) in that line?

Question

I was taught, of course, that the average of something is the sum of all the parts divided by the number of those parts.

This is easy when it is a set of values(2, 6, 8) because its simply (2+6+8)/3 = 16/3 ≈ 5.33.

But when you have a line, you have an **infinite amount of values** divided by **infinity**, right?

So how is it even possible to take the average? And why can you simply divide it by 2 when its a line?

And then of course there is the question about the average of curves and whatnot…

​

I feel so dumb, plz help me understand.

**Also this question comes from the idea that average velocity is half the final velocity**

Answer 1

The definition of average is a number where “half the values are on one side and half the values are on the other side”.
50% of Americans are below average intelligence, and will always be, because that’s what average is. It’s the “mid point” in a set of values where half is above and half is below
