The taxi fare is Rs.15 for the first km and Rs.8 for each additional km. Does the following situation form an AP?
Fare for the first km = ₹ 15
Fare for second km = ₹ (15+8)=₹ 23
Fare for third km = ₹ (23+8)=₹ 31
Hence, each subsequent term is obtained by adding a fixed number 8 to the previous term.
Hence it forms an AP.
