Halfway Between 45 and 402

When you ask "What number is halfway between 45 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=45 and Y=402.

Halfway Between Line

To find the number halfway between 45 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 402 into our formula, we get:

(45 + 402)/2 = 223.5

Thus, the number halfway between 45 and 402 is 223.5.

To check that our answer is correct, we subtract 45 from 223.5 and subtract 223.5 from 402 and compare the two numbers:

223.5 - 45 = 178.5
402 - 223.5 = 178.5

As you can see, the halfway number is 178.5 higher than 45 and 178.5 lower than 402. Therefore, our halfway between answer of 223.5 above is correct.
