Halfway Between 64 and 789

When you ask "What number is halfway between 64 and 789?" 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=789.

Halfway Between Line

To find the number halfway between 64 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 64 and 789 into our formula, we get:

(64 + 789)/2 = 426.5

Thus, the number halfway between 64 and 789 is 426.5.

To check that our answer is correct, we subtract 64 from 426.5 and subtract 426.5 from 789 and compare the two numbers:

426.5 - 64 = 362.5
789 - 426.5 = 362.5

As you can see, the halfway number is 362.5 higher than 64 and 362.5 lower than 789. Therefore, our halfway between answer of 426.5 above is correct.
