Halfway Between 90 and 625

When you ask "What number is halfway between 90 and 625?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=625.

Halfway Between Line

To find the number halfway between 90 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 625 into our formula, we get:

(90 + 625)/2 = 357.5

Thus, the number halfway between 90 and 625 is 357.5.

To check that our answer is correct, we subtract 90 from 357.5 and subtract 357.5 from 625 and compare the two numbers:

357.5 - 90 = 267.5
625 - 357.5 = 267.5

As you can see, the halfway number is 267.5 higher than 90 and 267.5 lower than 625. Therefore, our halfway between answer of 357.5 above is correct.
