Halfway Between 70 and 686

When you ask "What number is halfway between 70 and 686?" 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=686.

Halfway Between Line

To find the number halfway between 70 and 686, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 686 into our formula, we get:

(70 + 686)/2 = 378

Thus, the number halfway between 70 and 686 is 378.

To check that our answer is correct, we subtract 70 from 378 and subtract 378 from 686 and compare the two numbers:

378 - 70 = 308
686 - 378 = 308

As you can see, the halfway number is 308 higher than 70 and 308 lower than 686. Therefore, our halfway between answer of 378 above is correct.
