Halfway Between 51 and 351

When you ask "What number is halfway between 51 and 351?" 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=351.

Halfway Between Line

To find the number halfway between 51 and 351, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 351 into our formula, we get:

(51 + 351)/2 = 201

Thus, the number halfway between 51 and 351 is 201.

To check that our answer is correct, we subtract 51 from 201 and subtract 201 from 351 and compare the two numbers:

201 - 51 = 150
351 - 201 = 150

As you can see, the halfway number is 150 higher than 51 and 150 lower than 351. Therefore, our halfway between answer of 201 above is correct.
