<font face="Garamond" size="+2">


The elements of I are


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 1]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 2]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 3]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 4]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 5]


3 less than the smallest one is


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ -\ 3]


Then 3 less than the next smallest is


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ -\ 2]


And 3 less than the next smallest is


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ -\ 1]


On the other end,


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 6]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 7]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ n\ +\ 8]


Altogether, 6 additional elements.
