Halfway Between 67 and 643

When you ask "What number is halfway between 67 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=67 and Y=643.

Halfway Between Line

To find the number halfway between 67 and 643, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 643 into our formula, we get:

(67 + 643)/2 = 355

Thus, the number halfway between 67 and 643 is 355.

To check that our answer is correct, we subtract 67 from 355 and subtract 355 from 643 and compare the two numbers:

355 - 67 = 288
643 - 355 = 288

As you can see, the halfway number is 288 higher than 67 and 288 lower than 643. Therefore, our halfway between answer of 355 above is correct.
