Halfway Between 50 and 643

When you ask "What number is halfway between 50 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=50 and Y=643.

Halfway Between Line

To find the number halfway between 50 and 643, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 643 into our formula, we get:

(50 + 643)/2 = 346.5

Thus, the number halfway between 50 and 643 is 346.5.

To check that our answer is correct, we subtract 50 from 346.5 and subtract 346.5 from 643 and compare the two numbers:

346.5 - 50 = 296.5
643 - 346.5 = 296.5

As you can see, the halfway number is 296.5 higher than 50 and 296.5 lower than 643. Therefore, our halfway between answer of 346.5 above is correct.
