In which of the following situations, does the list of numbers involved make an arithmetic progression. and why?
The taxi fare after each km when the fare is Rs 20 for the first km and rises by Rs 8 for each additional km.
Tari fare for the first km = Rs.20
After each km it rises by Rs.8
The taxi fares are 20,28,36,44,52,60,......
The common difference is constant between any two terms, i.e 8
∴ It is an arithmetic progression.
