Halfway Between 5 and 309

When you ask "What number is halfway between 5 and 309?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=309.

Halfway Between Line

To find the number halfway between 5 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 309 into our formula, we get:

(5 + 309)/2 = 157

Thus, the number halfway between 5 and 309 is 157.

To check that our answer is correct, we subtract 5 from 157 and subtract 157 from 309 and compare the two numbers:

157 - 5 = 152
309 - 157 = 152

As you can see, the halfway number is 152 higher than 5 and 152 lower than 309. Therefore, our halfway between answer of 157 above is correct.
