To determine which sequence can be approximated by \(4n^3\), we would typically need to compare the given sequence with \(4n^3\) by evaluating their behavior as \(n\) becomes large.
In general, sequences that are polynomial functions of the same degree (in this case, degree 3) can often be approximated by each other. Specifically, if a sequence is of the form \(an^3 + bn^2 + cn + d\) (where \(a\), \(b\), \(c\), and \(d\) are constants), then for large \(n\), the \(n^3\) term will dominate, and the sequence can be approximated by \(an^3\).
So, to find a sequence that can be approximated by \(4n^3\), look for a sequence of the form \(4n^3 + k\), \(3n^3 + m\), or generally \(an^3\) where \(a\) is a constant close to 4.
If you provide specific sequences to evaluate, I can determine if they can be approximated by \(4n^3\).
