Reasonable because the three items altogether cost about $40
1. common differece, d = a2 - a1d = -8 - 9 = -17d = -25 - (-8) = -17
2. first is solve the common differece,dd = 10.5 - 13 = -2.5so an = 15.5 - 2.5n is the answer
3. a(x) = 440 + 65xwhere x is the number of weeksa(25) = 440 + 65(25)a(25) = $2065
