It is known that, a sequence is arithmetic when the differences between consecutive terms are the same. Calculate the difference between a2 and a1
d1=a2a1=21=1 Similarly d2=a3a2=42=2 d3=a4a3=84=4 d4=a5a4=168=8 From above calculte the differences between each two terms is not common. So, the sequence is not arithmetic.
