Halfway Between 70 and 690

When you ask "What number is halfway between 70 and 690?" 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=690.

Halfway Between Line

To find the number halfway between 70 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 690 into our formula, we get:

(70 + 690)/2 = 380

Thus, the number halfway between 70 and 690 is 380.

To check that our answer is correct, we subtract 70 from 380 and subtract 380 from 690 and compare the two numbers:

380 - 70 = 310
690 - 380 = 310

As you can see, the halfway number is 310 higher than 70 and 310 lower than 690. Therefore, our halfway between answer of 380 above is correct.
