Halfway Between 90 and 170

When you ask "What number is halfway between 90 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=90 and Y=170.

Halfway Between Line

To find the number halfway between 90 and 170, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 170 into our formula, we get:

(90 + 170)/2 = 130

Thus, the number halfway between 90 and 170 is 130.

To check that our answer is correct, we subtract 90 from 130 and subtract 130 from 170 and compare the two numbers:

130 - 90 = 40
170 - 130 = 40

As you can see, the halfway number is 40 higher than 90 and 40 lower than 170. Therefore, our halfway between answer of 130 above is correct.
