No, because the total fare (in Rs.) after each km is 15,(15+ 8), (15 + 2 x 8), (15+ 3 x 8),…= 15,23, 31, 39,…
Let t1 = 15,t= 23,t= 31 and t= 39
Now, t2 - t1 = 23 - 15 = 8
t3 - t= 31 - 23 = 8
t4 - t3 = 39 - 31 = 8
Since, all the successive terms of the given list have same difference i.e., common difference = 8
Hence, the total fare after each km form an AP.
