Halfway Between 90 and 150

When you ask "What number is halfway between 90 and 150?" 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=150.

Halfway Between Line

To find the number halfway between 90 and 150, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 150 into our formula, we get:

(90 + 150)/2 = 120

Thus, the number halfway between 90 and 150 is 120.

To check that our answer is correct, we subtract 90 from 120 and subtract 120 from 150 and compare the two numbers:

120 - 90 = 30
150 - 120 = 30

As you can see, the halfway number is 30 higher than 90 and 30 lower than 150. Therefore, our halfway between answer of 120 above is correct.
