w,x,y,z is an arithmetic sequence, which of the following options also qualifies as an arithmetiv sequence?
I. w-6,x-6,y-6,z-6
II. 5w,2x,3y,5z
III. 5w,5x,5y,5z Answers
A) II and III	B) III only	C) I and III	D) I and II	E) II only
lets look at the three choices...   I. w-6,x-6,y-6,z-6   since the difference is constant, it is an arithmetic sequence...   II. 5w,2x,3y,5z   since the difference is not constant, it is not an arithmetic sequence   III. 5w,5x,5y,5z   since the difference is constant it is an arithmetic sequence...   II and IIInswer is II and III)
