Halfway Between 51 and 310

When you ask "What number is halfway between 51 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=51 and Y=310.

Halfway Between Line

To find the number halfway between 51 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 310 into our formula, we get:

(51 + 310)/2 = 180.5

Thus, the number halfway between 51 and 310 is 180.5.

To check that our answer is correct, we subtract 51 from 180.5 and subtract 180.5 from 310 and compare the two numbers:

180.5 - 51 = 129.5
310 - 180.5 = 129.5

As you can see, the halfway number is 129.5 higher than 51 and 129.5 lower than 310. Therefore, our halfway between answer of 180.5 above is correct.
