Halfway Between 90 and 257

When you ask "What number is halfway between 90 and 257?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=257.

Halfway Between Line

To find the number halfway between 90 and 257, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 257 into our formula, we get:

(90 + 257)/2 = 173.5

Thus, the number halfway between 90 and 257 is 173.5.

To check that our answer is correct, we subtract 90 from 173.5 and subtract 173.5 from 257 and compare the two numbers:

173.5 - 90 = 83.5
257 - 173.5 = 83.5

As you can see, the halfway number is 83.5 higher than 90 and 83.5 lower than 257. Therefore, our halfway between answer of 173.5 above is correct.
