Which of the following options is an arithmetic sequence?
I. m-9, n-5, o-9,p-9, q-9, r-9
II. m^5, n^5, o^5, p^5, q^5
III. 4m,4n,4o,4p,4q
Answers: A) I only B) I and II C) I and III D) II and III E) III only
lets look at the three choices...   I. m-9, n-5, o-9,p-9, q-9, r-9   since the difference is not constant, it is not an arithmetic sequence...   II. m^5, n^5, o^5, p^5, q^5   since the difference is not constant, it is not an arithmetic sequence   III. 4m,4n,4o,4p,4q   since the difference is constant it is an arithmetic sequence...   The answer is III only)
