Halfway Between 51 and 121

When you ask "What number is halfway between 51 and 121?" 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=121.

Halfway Between Line

To find the number halfway between 51 and 121, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 121 into our formula, we get:

(51 + 121)/2 = 86

Thus, the number halfway between 51 and 121 is 86.

To check that our answer is correct, we subtract 51 from 86 and subtract 86 from 121 and compare the two numbers:

86 - 51 = 35
121 - 86 = 35

As you can see, the halfway number is 35 higher than 51 and 35 lower than 121. Therefore, our halfway between answer of 86 above is correct.
