Halfway Between 100 and 743

When you ask "What number is halfway between 100 and 743?" 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=743.

Halfway Between Line

To find the number halfway between 100 and 743, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 743 into our formula, we get:

(100 + 743)/2 = 421.5

Thus, the number halfway between 100 and 743 is 421.5.

To check that our answer is correct, we subtract 100 from 421.5 and subtract 421.5 from 743 and compare the two numbers:

421.5 - 100 = 321.5
743 - 421.5 = 321.5

As you can see, the halfway number is 321.5 higher than 100 and 321.5 lower than 743. Therefore, our halfway between answer of 421.5 above is correct.
