Halfway Between 90 and 620

When you ask "What number is halfway between 90 and 620?" 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=620.

Halfway Between Line

To find the number halfway between 90 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 620 into our formula, we get:

(90 + 620)/2 = 355

Thus, the number halfway between 90 and 620 is 355.

To check that our answer is correct, we subtract 90 from 355 and subtract 355 from 620 and compare the two numbers:

355 - 90 = 265
620 - 355 = 265

As you can see, the halfway number is 265 higher than 90 and 265 lower than 620. Therefore, our halfway between answer of 355 above is correct.
