Halfway Between 64 and 839

When you ask "What number is halfway between 64 and 839?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=64 and Y=839.

Halfway Between Line

To find the number halfway between 64 and 839, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 64 and 839 into our formula, we get:

(64 + 839)/2 = 451.5

Thus, the number halfway between 64 and 839 is 451.5.

To check that our answer is correct, we subtract 64 from 451.5 and subtract 451.5 from 839 and compare the two numbers:

451.5 - 64 = 387.5
839 - 451.5 = 387.5

As you can see, the halfway number is 387.5 higher than 64 and 387.5 lower than 839. Therefore, our halfway between answer of 451.5 above is correct.
