Halfway Between 100 and 170

When you ask "What number is halfway between 100 and 170?" 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=170.

Halfway Between Line

To find the number halfway between 100 and 170, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 170 into our formula, we get:

(100 + 170)/2 = 135

Thus, the number halfway between 100 and 170 is 135.

To check that our answer is correct, we subtract 100 from 135 and subtract 135 from 170 and compare the two numbers:

135 - 100 = 35
170 - 135 = 35

As you can see, the halfway number is 35 higher than 100 and 35 lower than 170. Therefore, our halfway between answer of 135 above is correct.
