Halfway Between 90 and 278

When you ask "What number is halfway between 90 and 278?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=278.

Halfway Between Line

To find the number halfway between 90 and 278, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 278 into our formula, we get:

(90 + 278)/2 = 184

Thus, the number halfway between 90 and 278 is 184.

To check that our answer is correct, we subtract 90 from 184 and subtract 184 from 278 and compare the two numbers:

184 - 90 = 94
278 - 184 = 94

As you can see, the halfway number is 94 higher than 90 and 94 lower than 278. Therefore, our halfway between answer of 184 above is correct.
