Short Answer TypeIn which of the following situations, does the list of numbers involved make an 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.
of the air remaining in the cylinder at a time.Write first four terms of the AP, when the first term a and the common difference d are given as follows:
a – 10, d = 10
a = 10, d = 10
First term = a = 10
Second term = 18 + d = 10+ 10 = 20
Third term = 20 + d = 20 + 10 = 30
Fourth term = 30 + d = 30 + 10 = 40
Hence, first four terms of the given A .P. are 10, 20, 30, 40.
Write first four terms of the AP, when the first term a and the common difference d are given as follows:
a = –2, d = 0
Write first four terms of the AP, when the first term a and the common difference d are given as follows:
a = 4, d = – 3
Write first four terms of the AP, when the first term a and the common difference d are given as follows:
a = – 1, d =
