Halfway Between 5 and 643

When you ask "What number is halfway between 5 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=5 and Y=643.

Halfway Between Line

To find the number halfway between 5 and 643, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 643 into our formula, we get:

(5 + 643)/2 = 324

Thus, the number halfway between 5 and 643 is 324.

To check that our answer is correct, we subtract 5 from 324 and subtract 324 from 643 and compare the two numbers:

324 - 5 = 319
643 - 324 = 319

As you can see, the halfway number is 319 higher than 5 and 319 lower than 643. Therefore, our halfway between answer of 324 above is correct.
