Halfway Between 51 and 345

When you ask "What number is halfway between 51 and 345?" 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=345.

Halfway Between Line

To find the number halfway between 51 and 345, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 345 into our formula, we get:

(51 + 345)/2 = 198

Thus, the number halfway between 51 and 345 is 198.

To check that our answer is correct, we subtract 51 from 198 and subtract 198 from 345 and compare the two numbers:

198 - 51 = 147
345 - 198 = 147

As you can see, the halfway number is 147 higher than 51 and 147 lower than 345. Therefore, our halfway between answer of 198 above is correct.
