Halfway Between 30 and 757

When you ask "What number is halfway between 30 and 757?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=757.

Halfway Between Line

To find the number halfway between 30 and 757, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 757 into our formula, we get:

(30 + 757)/2 = 393.5

Thus, the number halfway between 30 and 757 is 393.5.

To check that our answer is correct, we subtract 30 from 393.5 and subtract 393.5 from 757 and compare the two numbers:

393.5 - 30 = 363.5
757 - 393.5 = 363.5

As you can see, the halfway number is 363.5 higher than 30 and 363.5 lower than 757. Therefore, our halfway between answer of 393.5 above is correct.
