Halfway Between 55 and 150

When you ask "What number is halfway between 55 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=55 and Y=150.

Halfway Between Line

To find the number halfway between 55 and 150, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 150 into our formula, we get:

(55 + 150)/2 = 102.5

Thus, the number halfway between 55 and 150 is 102.5.

To check that our answer is correct, we subtract 55 from 102.5 and subtract 102.5 from 150 and compare the two numbers:

102.5 - 55 = 47.5
150 - 102.5 = 47.5

As you can see, the halfway number is 47.5 higher than 55 and 47.5 lower than 150. Therefore, our halfway between answer of 102.5 above is correct.
