What is the change between pairs of consecutive terms?
4
Practice makes perfect
By observing the change that occurs between consecutive terms, we can determine the common difference of the arithmetic sequence. Here, we can see that each term is 4 more than the previous term.
- 16+ 4 âź¶- 12+ 4 âź¶- 8+ 4 âź¶- 4+ 4 âź¶...
Therefore, the common difference is 4.
