Which of the following are arithmetic sequences, which are geometric sequences, and which are neither?
(a) 5, 10, 20, 40, 80,
Describe the sequence and the change in it.
(b) 3, 8, 13, 18, 23, 28,
Describe the sequence and the change in it.
(c) 1, 4, 9, 16, 25
Describe the sequence and the change in it.
(a) 5, 10, 20, 40, 80,---
So given sequence is geometric sequence
(b) 3, 8, 13, 18, 23, 28,---
So given sequence is Arithmetic sequence
(c)1, 4, 9, 16, 25,---
So given sequence is neither arithmetic nor geometric
