Halfway Between 15 and 171

When you ask "What number is halfway between 15 and 171?" 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=171.

Halfway Between Line

To find the number halfway between 15 and 171, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 171 into our formula, we get:

(15 + 171)/2 = 93

Thus, the number halfway between 15 and 171 is 93.

To check that our answer is correct, we subtract 15 from 93 and subtract 93 from 171 and compare the two numbers:

93 - 15 = 78
171 - 93 = 78

As you can see, the halfway number is 78 higher than 15 and 78 lower than 171. Therefore, our halfway between answer of 93 above is correct.
