Question

the taxi fare after each km when the fare is Rs.15 for the first km and Rs.8 for each additional km.
does the list of numbers involved make an AP , and why ?

Answer 1

Answer:

AP- 15,23,31,39,47.....

Step-by-step explanation:

As the question states

a=15

D=8

the first term: a= 15

second term: a+D= 15+8=23

and so on

Answer 2

Answer:

We can write the given condition as;

Taxi fare for 1 km = 15

Taxi fare for first 2 kms = 15+8 = 23

Taxi fare for first 3 kms = 23+8 = 31

Taxi fare for first 4 kms = 31+8 = 39

And so on……

Thus, 15, 23, 31, 39 … forms an A.P. because every next term is 8 more than the preceding term.
