Halfway Between 70 and 310

When you ask "What number is halfway between 70 and 310?" 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=310.

Halfway Between Line

To find the number halfway between 70 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 310 into our formula, we get:

(70 + 310)/2 = 190

Thus, the number halfway between 70 and 310 is 190.

To check that our answer is correct, we subtract 70 from 190 and subtract 190 from 310 and compare the two numbers:

190 - 70 = 120
310 - 190 = 120

As you can see, the halfway number is 120 higher than 70 and 120 lower than 310. Therefore, our halfway between answer of 190 above is correct.
