Halfway Between 100 and 710

When you ask "What number is halfway between 100 and 710?" 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=710.

Halfway Between Line

To find the number halfway between 100 and 710, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 710 into our formula, we get:

(100 + 710)/2 = 405

Thus, the number halfway between 100 and 710 is 405.

To check that our answer is correct, we subtract 100 from 405 and subtract 405 from 710 and compare the two numbers:

405 - 100 = 305
710 - 405 = 305

As you can see, the halfway number is 305 higher than 100 and 305 lower than 710. Therefore, our halfway between answer of 405 above is correct.
