Halfway Between 70 and 620

When you ask "What number is halfway between 70 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=70 and Y=620.

Halfway Between Line

To find the number halfway between 70 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 620 into our formula, we get:

(70 + 620)/2 = 345

Thus, the number halfway between 70 and 620 is 345.

To check that our answer is correct, we subtract 70 from 345 and subtract 345 from 620 and compare the two numbers:

345 - 70 = 275
620 - 345 = 275

As you can see, the halfway number is 275 higher than 70 and 275 lower than 620. Therefore, our halfway between answer of 345 above is correct.
