Halfway Between 35 and 643

When you ask "What number is halfway between 35 and 643?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=35 and Y=643.

Halfway Between Line

To find the number halfway between 35 and 643, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 35 and 643 into our formula, we get:

(35 + 643)/2 = 339

Thus, the number halfway between 35 and 643 is 339.

To check that our answer is correct, we subtract 35 from 339 and subtract 339 from 643 and compare the two numbers:

339 - 35 = 304
643 - 339 = 304

As you can see, the halfway number is 304 higher than 35 and 304 lower than 643. Therefore, our halfway between answer of 339 above is correct.
