If a,b,c,d,e is an arithmetic sequence which of the following is also an arithmetic sequence?
I. 5a, 5b, 5c, 5d, 5e
II. a-6, b-6, c-6, d-6, e-6
III. a^8, b^8, c^8, d^8, e^8	Choose the most appropriate option
A) I and II B) II only C) II and III D) III only E) I only
lets look at the three choices...   I. 5a, 5b, 5c, 5d, 5e   since the difference is constant, it is an arithmetic sequence...   II. a-6, b-6, c-6, d-6, e-6   since the difference is constant, it is an arithmetic sequence   III. a^8, b^8, c^8, d^8, e^8   since the difference is not constant it is not be an arithmetic sequence...   only l and ll.. ans I and II....
