Determine if the sequence is convergent or divergent. Then, as \(n^5-n\) is divisible by both \(n\) and \(n+1\), it has at least one even factor and must therefore be even (the product of an even integer and any other integer is always even). Write the first four terms of the arithmetic sequence with a first term of 5 and a common difference of 3. In fact, any general term that is exponential in \(n\) is a geometric sequence.
