Halfway Between 1 and 310

When you ask "What number is halfway between 1 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=1 and Y=310.

Halfway Between Line

To find the number halfway between 1 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 310 into our formula, we get:

(1 + 310)/2 = 155.5

Thus, the number halfway between 1 and 310 is 155.5.

To check that our answer is correct, we subtract 1 from 155.5 and subtract 155.5 from 310 and compare the two numbers:

155.5 - 1 = 154.5
310 - 155.5 = 154.5

As you can see, the halfway number is 154.5 higher than 1 and 154.5 lower than 310. Therefore, our halfway between answer of 155.5 above is correct.
