Halfway Between 100 and 715

When you ask "What number is halfway between 100 and 715?" 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=715.

Halfway Between Line

To find the number halfway between 100 and 715, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 715 into our formula, we get:

(100 + 715)/2 = 407.5

Thus, the number halfway between 100 and 715 is 407.5.

To check that our answer is correct, we subtract 100 from 407.5 and subtract 407.5 from 715 and compare the two numbers:

407.5 - 100 = 307.5
715 - 407.5 = 307.5

As you can see, the halfway number is 307.5 higher than 100 and 307.5 lower than 715. Therefore, our halfway between answer of 407.5 above is correct.
