55. To find a number halfway between two numbers on the number line, add the two numbers together and divide by 2, so (82 + 28)/2 = 110/2 = 55. Check the answer: 55-28 = 27, and 82-55 = 27.
Example: what is half way between 4 and 6 (the obvious answer is 5), but work it through: (4+6)/2 = 10/2 = 5.
