Chapter 18 Collecting and Describing Data

(p. 515):

Sample response:
8, 9, 11, 13, 15, 196.
It was necessary to make the middle number 12, so you can use11 and 13 as the two middle numbers.
The total of the 6 numbers had to be 42 × 6 = 252.
If you just choose the two numbers less than 11 to be 8 and 9 and one number greater than 13 to be 15, you just subtract the total of 8, 9, 11, 13, and 15 from 252 to get the last number.
