When you ask "What number is halfway between 18 and 155?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=18 and Y=155.
To find the number halfway between 18 and 155, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 18 and 155 into our formula, we get:
(18 + 155)/2 = 86.5
Thus, the number halfway between 18 and 155 is 86.5.
To check that our answer is correct, we subtract 18 from 86.5 and subtract 86.5 from 155 and compare the two numbers:
86.5 - 18 = 68.5
155 - 86.5 = 68.5
As you can see, the halfway number is 68.5 higher than 18 and 68.5 lower than 155. Therefore, our halfway between answer of 86.5 above is correct.
