Halfway Between 43 and 86

When you ask "What number is halfway between 43 and 86?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=43 and Y=86.

Halfway Between Line

To find the number halfway between 43 and 86, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 86 into our formula, we get:

(43 + 86)/2 = 64.5

Thus, the number halfway between 43 and 86 is 64.5.

To check that our answer is correct, we subtract 43 from 64.5 and subtract 64.5 from 86 and compare the two numbers:

64.5 - 43 = 21.5
86 - 64.5 = 21.5

As you can see, the halfway number is 21.5 higher than 43 and 21.5 lower than 86. Therefore, our halfway between answer of 64.5 above is correct.
