Halfway Between 100 and 757

When you ask "What number is halfway between 100 and 757?" 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=757.

Halfway Between Line

To find the number halfway between 100 and 757, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 757 into our formula, we get:

(100 + 757)/2 = 428.5

Thus, the number halfway between 100 and 757 is 428.5.

To check that our answer is correct, we subtract 100 from 428.5 and subtract 428.5 from 757 and compare the two numbers:

428.5 - 100 = 328.5
757 - 428.5 = 328.5

As you can see, the halfway number is 328.5 higher than 100 and 328.5 lower than 757. Therefore, our halfway between answer of 428.5 above is correct.
