Halfway Between 51 and 307

When you ask "What number is halfway between 51 and 307?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=51 and Y=307.

Halfway Between Line

To find the number halfway between 51 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 307 into our formula, we get:

(51 + 307)/2 = 179

Thus, the number halfway between 51 and 307 is 179.

To check that our answer is correct, we subtract 51 from 179 and subtract 179 from 307 and compare the two numbers:

179 - 51 = 128
307 - 179 = 128

As you can see, the halfway number is 128 higher than 51 and 128 lower than 307. Therefore, our halfway between answer of 179 above is correct.
