Halfway Between 30 and 145

When you ask "What number is halfway between 30 and 145?" 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=145.

Halfway Between Line

To find the number halfway between 30 and 145, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 145 into our formula, we get:

(30 + 145)/2 = 87.5

Thus, the number halfway between 30 and 145 is 87.5.

To check that our answer is correct, we subtract 30 from 87.5 and subtract 87.5 from 145 and compare the two numbers:

87.5 - 30 = 57.5
145 - 87.5 = 57.5

As you can see, the halfway number is 57.5 higher than 30 and 57.5 lower than 145. Therefore, our halfway between answer of 87.5 above is correct.
