When you ask "What number is halfway between 7 and 620?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=7 and Y=620.
To find the number halfway between 7 and 620, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 620 into our formula, we get:
(7 + 620)/2 = 313.5
Thus, the number halfway between 7 and 620 is 313.5.
To check that our answer is correct, we subtract 7 from 313.5 and subtract 313.5 from 620 and compare the two numbers:
313.5 - 7 = 306.5
620 - 313.5 = 306.5
As you can see, the halfway number is 306.5 higher than 7 and 306.5 lower than 620. Therefore, our halfway between answer of 313.5 above is correct.
