Halfway Between 55 and 402

When you ask "What number is halfway between 55 and 402?" 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=402.

Halfway Between Line

To find the number halfway between 55 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 402 into our formula, we get:

(55 + 402)/2 = 228.5

Thus, the number halfway between 55 and 402 is 228.5.

To check that our answer is correct, we subtract 55 from 228.5 and subtract 228.5 from 402 and compare the two numbers:

228.5 - 55 = 173.5
402 - 228.5 = 173.5

As you can see, the halfway number is 173.5 higher than 55 and 173.5 lower than 402. Therefore, our halfway between answer of 228.5 above is correct.
