Show that each sequence is arithmetic. Find the common difference, and list the first four terms. $$ \left\{s_{n}\right\}=\{n-5\} $$
Added by Susan F.
Step 1
An arithmetic sequence has a common difference between consecutive terms. In this case, the sequence is given by the formula $s_n = n - 5$. Let's find the difference between consecutive terms: $s_{n+1} - s_n = (n+1-5) - (n-5) = n+1-5-n+5 = 1$ Since the Show more…
