Halfway Between 55 and 658

When you ask "What number is halfway between 55 and 658?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=658.

Halfway Between Line

To find the number halfway between 55 and 658, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 658 into our formula, we get:

(55 + 658)/2 = 356.5

Thus, the number halfway between 55 and 658 is 356.5.

To check that our answer is correct, we subtract 55 from 356.5 and subtract 356.5 from 658 and compare the two numbers:

356.5 - 55 = 301.5
658 - 356.5 = 301.5

As you can see, the halfway number is 301.5 higher than 55 and 301.5 lower than 658. Therefore, our halfway between answer of 356.5 above is correct.
