Halfway Between 100 and 516

When you ask "What number is halfway between 100 and 516?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=516.

Halfway Between Line

To find the number halfway between 100 and 516, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 516 into our formula, we get:

(100 + 516)/2 = 308

Thus, the number halfway between 100 and 516 is 308.

To check that our answer is correct, we subtract 100 from 308 and subtract 308 from 516 and compare the two numbers:

308 - 100 = 208
516 - 308 = 208

As you can see, the halfway number is 208 higher than 100 and 208 lower than 516. Therefore, our halfway between answer of 308 above is correct.
