Is the Sequence Arithmetic? Yes Common Difference: 13
Practice makes perfect
When a sequence is arithmetic, the difference between any two consecutive terms is constant. By examining our sequence, we can see that this is the case.
13 + 13 âź¶ 26 + 13 âź¶ 39 + 13 âź¶ 52 + 13 âź¶ ...
Therefore, the sequence is arithmetic and the common difference is 13.
