Halfway Between 57 and 254

When you ask "What number is halfway between 57 and 254?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=57 and Y=254.

Halfway Between Line

To find the number halfway between 57 and 254, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 57 and 254 into our formula, we get:

(57 + 254)/2 = 155.5

Thus, the number halfway between 57 and 254 is 155.5.

To check that our answer is correct, we subtract 57 from 155.5 and subtract 155.5 from 254 and compare the two numbers:

155.5 - 57 = 98.5
254 - 155.5 = 98.5

As you can see, the halfway number is 98.5 higher than 57 and 98.5 lower than 254. Therefore, our halfway between answer of 155.5 above is correct.
