When you ask "What number is halfway between 49 and 170?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=49 and Y=170.
To find the number halfway between 49 and 170, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 49 and 170 into our formula, we get:
(49 + 170)/2 = 109.5
Thus, the number halfway between 49 and 170 is 109.5.
To check that our answer is correct, we subtract 49 from 109.5 and subtract 109.5 from 170 and compare the two numbers:
109.5 - 49 = 60.5
170 - 109.5 = 60.5
As you can see, the halfway number is 60.5 higher than 49 and 60.5 lower than 170. Therefore, our halfway between answer of 109.5 above is correct.
