Halfway Between 90 and 428

When you ask "What number is halfway between 90 and 428?" 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=428.

Halfway Between Line

To find the number halfway between 90 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 428 into our formula, we get:

(90 + 428)/2 = 259

Thus, the number halfway between 90 and 428 is 259.

To check that our answer is correct, we subtract 90 from 259 and subtract 259 from 428 and compare the two numbers:

259 - 90 = 169
428 - 259 = 169

As you can see, the halfway number is 169 higher than 90 and 169 lower than 428. Therefore, our halfway between answer of 259 above is correct.
