Halfway Between 87 and 789

When you ask "What number is halfway between 87 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=87 and Y=789.

Halfway Between Line

To find the number halfway between 87 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 789 into our formula, we get:

(87 + 789)/2 = 438

Thus, the number halfway between 87 and 789 is 438.

To check that our answer is correct, we subtract 87 from 438 and subtract 438 from 789 and compare the two numbers:

438 - 87 = 351
789 - 438 = 351

As you can see, the halfway number is 351 higher than 87 and 351 lower than 789. Therefore, our halfway between answer of 438 above is correct.
