Halfway Between 85 and 620

When you ask "What number is halfway between 85 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=85 and Y=620.

Halfway Between Line

To find the number halfway between 85 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 620 into our formula, we get:

(85 + 620)/2 = 352.5

Thus, the number halfway between 85 and 620 is 352.5.

To check that our answer is correct, we subtract 85 from 352.5 and subtract 352.5 from 620 and compare the two numbers:

352.5 - 85 = 267.5
620 - 352.5 = 267.5

As you can see, the halfway number is 267.5 higher than 85 and 267.5 lower than 620. Therefore, our halfway between answer of 352.5 above is correct.
