It is known that, a sequence is arithmetic when the differences between consecutive terms are the same. Calculate the difference between \(a_2\ and\ a_1\)
\(d_1 = a_2 - a_1 =2-1=1\) Similarly \(d_2 = a_3 - a_2 =4-2=2\) \(d_3 = a_4 - a_3 =8-4=4\) \(d_4 = a_5 - a_4 =16-8=8\) From above calculte the differences between each two terms is not common. So, the sequence is not arithmetic.
