Arithmetic sequence terms and sum
The first three terms of an arithmetic sequence are \(0, 3, 6\). Find the common difference \(d\), write the nth-term rule \(u_n\), then calculate \(u_11\) and \(S_11\).
Worked practice: sequences and series
Find the common change or ratio, then use it to calculate the requested term or sum.
