Halfway Between 70 and 642

When you ask "What number is halfway between 70 and 642?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=70 and Y=642.

Halfway Between Line

To find the number halfway between 70 and 642, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 642 into our formula, we get:

(70 + 642)/2 = 356

Thus, the number halfway between 70 and 642 is 356.

To check that our answer is correct, we subtract 70 from 356 and subtract 356 from 642 and compare the two numbers:

356 - 70 = 286
642 - 356 = 286

As you can see, the halfway number is 286 higher than 70 and 286 lower than 642. Therefore, our halfway between answer of 356 above is correct.
