Halfway Between 100 and 507

When you ask "What number is halfway between 100 and 507?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=507.

Halfway Between Line

To find the number halfway between 100 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 507 into our formula, we get:

(100 + 507)/2 = 303.5

Thus, the number halfway between 100 and 507 is 303.5.

To check that our answer is correct, we subtract 100 from 303.5 and subtract 303.5 from 507 and compare the two numbers:

303.5 - 100 = 203.5
507 - 303.5 = 203.5

As you can see, the halfway number is 203.5 higher than 100 and 203.5 lower than 507. Therefore, our halfway between answer of 303.5 above is correct.
