Imp Question

1. The auto fare after each kilometer when the fare is Rs 5/- for the first kilometer and Rs 3/- for each additional kilometer.

Initial Auto fare = Rs.5

At every km Rs. 3 is added.

So, the series for fare after each km will be given by 5,5+3,5+3+3....

So the required series 5, 8, 11, 14.....

Since the common difference is constant

i.e 8 - 3 = 11 - 8 = 3

Similarly do the next one.
