Halfway Between 100 and 705

When you ask "What number is halfway between 100 and 705?" 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=705.

Halfway Between Line

To find the number halfway between 100 and 705, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 705 into our formula, we get:

(100 + 705)/2 = 402.5

Thus, the number halfway between 100 and 705 is 402.5.

To check that our answer is correct, we subtract 100 from 402.5 and subtract 402.5 from 705 and compare the two numbers:

402.5 - 100 = 302.5
705 - 402.5 = 302.5

As you can see, the halfway number is 302.5 higher than 100 and 302.5 lower than 705. Therefore, our halfway between answer of 402.5 above is correct.
