Halfway Between 50 and 689

When you ask "What number is halfway between 50 and 689?" 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=689.

Halfway Between Line

To find the number halfway between 50 and 689, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 689 into our formula, we get:

(50 + 689)/2 = 369.5

Thus, the number halfway between 50 and 689 is 369.5.

To check that our answer is correct, we subtract 50 from 369.5 and subtract 369.5 from 689 and compare the two numbers:

369.5 - 50 = 319.5
689 - 369.5 = 319.5

As you can see, the halfway number is 319.5 higher than 50 and 319.5 lower than 689. Therefore, our halfway between answer of 369.5 above is correct.
