Halfway Between 55 and 901

When you ask "What number is halfway between 55 and 901?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=901.

Halfway Between Line

To find the number halfway between 55 and 901, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 901 into our formula, we get:

(55 + 901)/2 = 478

Thus, the number halfway between 55 and 901 is 478.

To check that our answer is correct, we subtract 55 from 478 and subtract 478 from 901 and compare the two numbers:

478 - 55 = 423
901 - 478 = 423

As you can see, the halfway number is 423 higher than 55 and 423 lower than 901. Therefore, our halfway between answer of 478 above is correct.
