Halfway Between 31 and 98

When you ask "What number is halfway between 31 and 98?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=31 and Y=98.

Halfway Between Line

To find the number halfway between 31 and 98, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 98 into our formula, we get:

(31 + 98)/2 = 64.5

Thus, the number halfway between 31 and 98 is 64.5.

To check that our answer is correct, we subtract 31 from 64.5 and subtract 64.5 from 98 and compare the two numbers:

64.5 - 31 = 33.5
98 - 64.5 = 33.5

As you can see, the halfway number is 33.5 higher than 31 and 33.5 lower than 98. Therefore, our halfway between answer of 64.5 above is correct.
