Halfway Between 70 and 621

When you ask "What number is halfway between 70 and 621?" 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=621.

Halfway Between Line

To find the number halfway between 70 and 621, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 621 into our formula, we get:

(70 + 621)/2 = 345.5

Thus, the number halfway between 70 and 621 is 345.5.

To check that our answer is correct, we subtract 70 from 345.5 and subtract 345.5 from 621 and compare the two numbers:

345.5 - 70 = 275.5
621 - 345.5 = 275.5

As you can see, the halfway number is 275.5 higher than 70 and 275.5 lower than 621. Therefore, our halfway between answer of 345.5 above is correct.
