When you ask "What number is halfway between 5 and 138?" 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=138.
To find the number halfway between 5 and 138, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 5 and 138 into our formula, we get:
(5 + 138)/2 = 71.5
Thus, the number halfway between 5 and 138 is 71.5.
To check that our answer is correct, we subtract 5 from 71.5 and subtract 71.5 from 138 and compare the two numbers:
71.5 - 5 = 66.5
138 - 71.5 = 66.5
As you can see, the halfway number is 66.5 higher than 5 and 66.5 lower than 138. Therefore, our halfway between answer of 71.5 above is correct.
