Halfway Between 4 and 291

When you ask "What number is halfway between 4 and 291?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=291.

Halfway Between Line

To find the number halfway between 4 and 291, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 291 into our formula, we get:

(4 + 291)/2 = 147.5

Thus, the number halfway between 4 and 291 is 147.5.

To check that our answer is correct, we subtract 4 from 147.5 and subtract 147.5 from 291 and compare the two numbers:

147.5 - 4 = 143.5
291 - 147.5 = 143.5

As you can see, the halfway number is 143.5 higher than 4 and 143.5 lower than 291. Therefore, our halfway between answer of 147.5 above is correct.
