Halfway Between 15 and 148

When you ask "What number is halfway between 15 and 148?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=148.

Halfway Between Line

To find the number halfway between 15 and 148, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 148 into our formula, we get:

(15 + 148)/2 = 81.5

Thus, the number halfway between 15 and 148 is 81.5.

To check that our answer is correct, we subtract 15 from 81.5 and subtract 81.5 from 148 and compare the two numbers:

81.5 - 15 = 66.5
148 - 81.5 = 66.5

As you can see, the halfway number is 66.5 higher than 15 and 66.5 lower than 148. Therefore, our halfway between answer of 81.5 above is correct.
