Halfway Between 30 and 70

When you ask "What number is halfway between 30 and 70?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=70.

Halfway Between Line

To find the number halfway between 30 and 70, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 70 into our formula, we get:

(30 + 70)/2 = 50

Thus, the number halfway between 30 and 70 is 50.

To check that our answer is correct, we subtract 30 from 50 and subtract 50 from 70 and compare the two numbers:

50 - 30 = 20
70 - 50 = 20

As you can see, the halfway number is 20 higher than 30 and 20 lower than 70. Therefore, our halfway between answer of 50 above is correct.
