20 is between 10 and 30.
The question is: What is a Composite number between 10 and 20. First we must remember that a Composite number is a number that is divisible by itself, 1, and also another is considered a Composite number. Therefore, the Composite numbers between 10 and 20 are 10, 12, 14, 15, 16, 18 and 20. The other numbers are called Prime numbers.

The difference between the greatest and least number is the range. For example, if the greatest # in a set of data is 20, and the least # is 10, 20-10=10. 10 is the range.
The halfway point between two numbers is found by calculating the average of the two numbers. In this case, the average of -20 and 10 is (-20 + 10) / 2 = -10 / 2 = -5. Therefore, the number halfway between -20 and 10 is -5.
(10+20)/2 = 30/2 = 15
