Halfway Between 70 and 399

When you ask "What number is halfway between 70 and 399?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=70 and Y=399.

Halfway Between Line

To find the number halfway between 70 and 399, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 399 into our formula, we get:

(70 + 399)/2 = 234.5

Thus, the number halfway between 70 and 399 is 234.5.

To check that our answer is correct, we subtract 70 from 234.5 and subtract 234.5 from 399 and compare the two numbers:

234.5 - 70 = 164.5
399 - 234.5 = 164.5

As you can see, the halfway number is 164.5 higher than 70 and 164.5 lower than 399. Therefore, our halfway between answer of 234.5 above is correct.
