Halfway Between 85 and 402

When you ask "What number is halfway between 85 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=85 and Y=402.

Halfway Between Line

To find the number halfway between 85 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 402 into our formula, we get:

(85 + 402)/2 = 243.5

Thus, the number halfway between 85 and 402 is 243.5.

To check that our answer is correct, we subtract 85 from 243.5 and subtract 243.5 from 402 and compare the two numbers:

243.5 - 85 = 158.5
402 - 243.5 = 158.5

As you can see, the halfway number is 158.5 higher than 85 and 158.5 lower than 402. Therefore, our halfway between answer of 243.5 above is correct.
