Halfway Between 7 and 70

When you ask "What number is halfway between 7 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=7 and Y=70.

Halfway Between Line

To find the number halfway between 7 and 70, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 7 and 70 into our formula, we get:

(7 + 70)/2 = 38.5

Thus, the number halfway between 7 and 70 is 38.5.

To check that our answer is correct, we subtract 7 from 38.5 and subtract 38.5 from 70 and compare the two numbers:

38.5 - 7 = 31.5
70 - 38.5 = 31.5

As you can see, the halfway number is 31.5 higher than 7 and 31.5 lower than 70. Therefore, our halfway between answer of 38.5 above is correct.
