Well, darling, the number halfway between 11 and 15 is 13. You see, it's smack dab in the middle of those two numbers, like the cherry on top of a sundae. So, there you have it, 13 is the magic number in this case.
15 + 13 + 11 = 39
the next number is 5 and the one after that is 15
What would be the next number in this series 15 12 13 10 11 8?
11 13 15 18 20 20 The median is the middle number when they are in numerical order, so the median is 16.5. It is 16.5 because there is an even number of integers so you find the middle of 15 and 18
there is not one
19,17,15,13,11,9
11 and 13 are prime numbers but 15 is a composite number because it has more than two factors
The average of 9, 15, 11, and 13 is 12. It is calculated by adding all the numbers together (9+15+11+13 = 48) and then dividing by the total number of values (4).
11, 13, 15, 17, and 19 does.
