To tell whether the <span>the sequence is arithmetic, we try to see if there is a common difference between the terms in the sequence. We do as follows:
1 1/2 - 1 1/3 = 1/6 1 1/3 - 1 1/6 = 1/6
Therefore, the sequence is arithmetic and the common difference is 1/6. Hope this answers the questions. Have a nice day.</span>
