Given the following sequence:
[tex]10,\text{ 18, 26, 34, 42}[/tex]Observing the given sequence, it appears that the common difference between its two consecutive terms is 8.
42 - 34 = 8
34 - 26 = 8
26 - 18 = 8
18 - 10 = 8
Therefore, we can say that the sequence is Arithmetic and the rule is:
[tex]\text{ A}_n=A_1\text{ + (n - 1)d}[/tex][tex]\text{ A}_n=10\text{ + (n - 1)(8)}[/tex]
