Halfway Between 5 and 620

When you ask "What number is halfway between 5 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=5 and Y=620.

Halfway Between Line

To find the number halfway between 5 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 620 into our formula, we get:

(5 + 620)/2 = 312.5

Thus, the number halfway between 5 and 620 is 312.5.

To check that our answer is correct, we subtract 5 from 312.5 and subtract 312.5 from 620 and compare the two numbers:

312.5 - 5 = 307.5
620 - 312.5 = 307.5

As you can see, the halfway number is 307.5 higher than 5 and 307.5 lower than 620. Therefore, our halfway between answer of 312.5 above is correct.
