Ex 5.1, 1 In which of the following situations, does the list of numbers involved make as arithmetic progression and why? The taxi fare after each km when the fare is Rs 15 for the first km and Rs 8 for each additional km. Taxi fare for 1 km = Rs 15 Taxi fare for 2 km = 15 + 8 = Rs 23 Taxi fare for 3 km = 23 + 8 = Rs 31 Therefore, Series is 15, 23, 31 …….. Difference between 2nd term and 1st term = 23 – 15 = 8 Difference between 3rd term and 2nd term = 31 – 23 = 8 Since difference is same, it is an AP
