Halfway Between 78 and 402

When you ask "What number is halfway between 78 and 402?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=402.

Halfway Between Line

To find the number halfway between 78 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 402 into our formula, we get:

(78 + 402)/2 = 240

Thus, the number halfway between 78 and 402 is 240.

To check that our answer is correct, we subtract 78 from 240 and subtract 240 from 402 and compare the two numbers:

240 - 78 = 162
402 - 240 = 162

As you can see, the halfway number is 162 higher than 78 and 162 lower than 402. Therefore, our halfway between answer of 240 above is correct.
