Halfway Between 70 and 312

When you ask "What number is halfway between 70 and 312?" 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=312.

Halfway Between Line

To find the number halfway between 70 and 312, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 312 into our formula, we get:

(70 + 312)/2 = 191

Thus, the number halfway between 70 and 312 is 191.

To check that our answer is correct, we subtract 70 from 191 and subtract 191 from 312 and compare the two numbers:

191 - 70 = 121
312 - 191 = 121

As you can see, the halfway number is 121 higher than 70 and 121 lower than 312. Therefore, our halfway between answer of 191 above is correct.
