Halfway Between 90 and 153

When you ask "What number is halfway between 90 and 153?" 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=153.

Halfway Between Line

To find the number halfway between 90 and 153, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 153 into our formula, we get:

(90 + 153)/2 = 121.5

Thus, the number halfway between 90 and 153 is 121.5.

To check that our answer is correct, we subtract 90 from 121.5 and subtract 121.5 from 153 and compare the two numbers:

121.5 - 90 = 31.5
153 - 121.5 = 31.5

As you can see, the halfway number is 31.5 higher than 90 and 31.5 lower than 153. Therefore, our halfway between answer of 121.5 above is correct.
