Halfway Between 70 and 628

When you ask "What number is halfway between 70 and 628?" 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=628.

Halfway Between Line

To find the number halfway between 70 and 628, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 628 into our formula, we get:

(70 + 628)/2 = 349

Thus, the number halfway between 70 and 628 is 349.

To check that our answer is correct, we subtract 70 from 349 and subtract 349 from 628 and compare the two numbers:

349 - 70 = 279
628 - 349 = 279

As you can see, the halfway number is 279 higher than 70 and 279 lower than 628. Therefore, our halfway between answer of 349 above is correct.
