Halfway Between 100 and 402

When you ask "What number is halfway between 100 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=100 and Y=402.

Halfway Between Line

To find the number halfway between 100 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 402 into our formula, we get:

(100 + 402)/2 = 251

Thus, the number halfway between 100 and 402 is 251.

To check that our answer is correct, we subtract 100 from 251 and subtract 251 from 402 and compare the two numbers:

251 - 100 = 151
402 - 251 = 151

As you can see, the halfway number is 151 higher than 100 and 151 lower than 402. Therefore, our halfway between answer of 251 above is correct.
