If the average (arithmetic mean) of five consecutive negative integers is 6k – 1, what is the difference between the greatest and least of the five integers? Choose one:	A) 4K	B) 4k^2 -4k	C) 4-4k	D) 4	E) 4k+4
(n-2 + n - 1 + n + n + 1 + n + 2)/5 = 6k - 1   =&gt; n = 30k - 5   Greatest = n + 2 = 30k - 5 + 2 = 30k - 3   Least = n - 2 = 30k - 5 - 2   =&gt; 4ifference = 30k - 3 - (30k - 7)   = 4   Answer - 430  - 3 - (30  - 7)=
