We are given a sequence with the same difference between consecutive terms. We know it starts at \(-7\) and its \(4\)th term is \(11\). Find its \(12\)th term.
A sequence has \(n\)th term \(3n^2-4n+1\). In the sequence, there are two consecutive terms that sum to \(581\). Find the bigger one of these two terms?
We are given a sequence \( \left( \frac{n}{n+1} \right)_{n=1}^{\infty} \).
