Question
the sequences are arithmetic. Find(a) the common difference,(b) the eighth term,(c) a recursive rule for the $n$ th term, and(d) an explicit rule for the $n$ th term.$-2,1,4,7, \ldots$
Step 1
So, we subtract the first term from the second term: \[d = 1 - (-2) = 3\] So, the common difference, \(d\), is 3. Show more…
