An Arithmetic Sequence is defined as a sequence in which there is a common difference between consecutive terms.

Are the following sequences are arithmetic? If Yes, i dentify the common difference. YES YES YES NO NO

The general form of an ARITHMETIC sequence. First Term: Second Term: Third Term: Fourth Term: Fifth Term: nth Term:
