If the average (arithmetic mean) of five consecutive negative integers is 2k – 1, what is the difference W between the greatest and least of the five integers? Options.
A) 4K	B) 4k^2 -4k	C) 4-4k	D) 4	E) 4k+4
(n-2 + n - 1 + n + n + 1 + n + 2)/5 = 2k - 1   =&gt; n = 10k - 5   Greatest = n + 2 = 10k - 5 + 2 = 10k - 3   Least = n - 2 = 10k - 5 - 2   =&gt; 4ifference W= 10k - 3 - (10k - 7)   = 4   Answer - 410  - 3 - (10  - 7)=
