Which of the following are APs? If they form an AP, find the common difference d and write three more terms.
1, 3, 9, 27, . .
1, 3, 9, 27,.......
a2 – a1 = 3 – 1 = 2
a3 – a2 = 9 – 3 = 6
As a2 – ≠ a3 – a2
the given list of numbers does not form an A .P.
In 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.
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
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
