Answer:
Given,
a= 15
d= 8
that's why APs = a,a+d,a+2d,a+3d.....
= 15,15+8,15+2×8,15+3×8....
= 15,23,31,39....
why= when we take a2-a1=a3-a2
we ll get equal answer

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.
