Answer» No, the statement is not ture as the total fare (in Rs.) after each km is given as: 15, (15 + 8), (15 + 2 × 8), (15 + 3 × 8),… . = 15, 23, 31, 39,… Let t1= 15, t2= 23, t3= 31 and t4= 39 Now, d1= t2– t1= 23 – 5 = 8 d2= t3– t2= 33 – 23 = 8 And d3= t4– t3= 39 – 31 = 8 As d1= d2= d3, therefore given list of numbers formed by taking total fares after each Km forms an AP.

Answer»

No, the statement is not ture as the total fare (in Rs.) after each km is given as:

15, (15 + 8), (15 + 2 × 8), (15 + 3 × 8),… . = 15, 23, 31, 39,…

Let t1= 15, t2= 23, t3= 31 and t4= 39

Now, d1= t2– t1= 23 – 5 = 8

d2= t3– t2= 33 – 23 = 8

And d3= t4– t3= 39 – 31 = 8

As d1= d2= d3, therefore given list of numbers formed by taking total fares after each Km forms an AP.
