Halfway Between 100 and 190

When you ask "What number is halfway between 100 and 190?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=190.

Halfway Between Line

To find the number halfway between 100 and 190, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 190 into our formula, we get:

(100 + 190)/2 = 145

Thus, the number halfway between 100 and 190 is 145.

To check that our answer is correct, we subtract 100 from 145 and subtract 145 from 190 and compare the two numbers:

145 - 100 = 45
190 - 145 = 45

As you can see, the halfway number is 45 higher than 100 and 45 lower than 190. Therefore, our halfway between answer of 145 above is correct.
