Halfway Between 40 and 646

When you ask "What number is halfway between 40 and 646?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=646.

Halfway Between Line

To find the number halfway between 40 and 646, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 646 into our formula, we get:

(40 + 646)/2 = 343

Thus, the number halfway between 40 and 646 is 343.

To check that our answer is correct, we subtract 40 from 343 and subtract 343 from 646 and compare the two numbers:

343 - 40 = 303
646 - 343 = 303

As you can see, the halfway number is 303 higher than 40 and 303 lower than 646. Therefore, our halfway between answer of 343 above is correct.
