Detailed Solution

According to the question,
The total fare after each kilometer is, 15, 15+8, 15+2(8), 15+3(8) …….
= 15, 23, 31, 39, …
So, a=15,
d = 23-15=8,
31-23=8  As, all the terms have the same common difference which makes it an AP.
Therefore, the total fare after each kilometer forms an A.P. and the statement is proved to be true.
