Halfway Between 15 and 347

When you ask "What number is halfway between 15 and 347?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=347.

Halfway Between Line

To find the number halfway between 15 and 347, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 347 into our formula, we get:

(15 + 347)/2 = 181

Thus, the number halfway between 15 and 347 is 181.

To check that our answer is correct, we subtract 15 from 181 and subtract 181 from 347 and compare the two numbers:

181 - 15 = 166
347 - 181 = 166

As you can see, the halfway number is 166 higher than 15 and 166 lower than 347. Therefore, our halfway between answer of 181 above is correct.
