Halfway Between 55 and 654

When you ask "What number is halfway between 55 and 654?" 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=654.

Halfway Between Line

To find the number halfway between 55 and 654, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 654 into our formula, we get:

(55 + 654)/2 = 354.5

Thus, the number halfway between 55 and 654 is 354.5.

To check that our answer is correct, we subtract 55 from 354.5 and subtract 354.5 from 654 and compare the two numbers:

354.5 - 55 = 299.5
654 - 354.5 = 299.5

As you can see, the halfway number is 299.5 higher than 55 and 299.5 lower than 654. Therefore, our halfway between answer of 354.5 above is correct.
