Halfway Between 70 and 710

When you ask "What number is halfway between 70 and 710?" 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=710.

Halfway Between Line

To find the number halfway between 70 and 710, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 710 into our formula, we get:

(70 + 710)/2 = 390

Thus, the number halfway between 70 and 710 is 390.

To check that our answer is correct, we subtract 70 from 390 and subtract 390 from 710 and compare the two numbers:

390 - 70 = 320
710 - 390 = 320

As you can see, the halfway number is 320 higher than 70 and 320 lower than 710. Therefore, our halfway between answer of 390 above is correct.
