Halfway Between 21 and 70

When you ask "What number is halfway between 21 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=21 and Y=70.

Halfway Between Line

To find the number halfway between 21 and 70, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 70 into our formula, we get:

(21 + 70)/2 = 45.5

Thus, the number halfway between 21 and 70 is 45.5.

To check that our answer is correct, we subtract 21 from 45.5 and subtract 45.5 from 70 and compare the two numbers:

45.5 - 21 = 24.5
70 - 45.5 = 24.5

As you can see, the halfway number is 24.5 higher than 21 and 24.5 lower than 70. Therefore, our halfway between answer of 45.5 above is correct.
