Which of the following are APs? If they form an AP, find the common difference d and write three more terms.
a, a2 , a3 , a4 , . . .
a, a2, a3, a4, ..............
a2 – a1 = a2 – a = a(a – 1)
a3 – a2 = a3 – a2 = a2 (a – 1)
As a2 – a1 ≠ a3 – a2
the given list of numbers does not form an A .P.
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
Write first four terms of the AP, when the first term a and the common difference d are given as follows:
a = – 1.25, d = – 0.25
For the following APs, write the first term and the common difference
3, 1, – 1, – 3, . . .
