It seems that you're referring to a mathematical problem that involves identifying which sequences can be approximated by \(4n^3\). However, I cannot see the images or the specific sequences you mentioned.
In general, the expression \(4n^3\) is a cubic function, meaning that it can be used to approximate sequences that grow cubically. Here are some kinds of sequences that might be approximated by \(4n^3\):
- Cubic Sequences: Sequences of the form \(an^3\) for some constant \(a\).
- Polynomial Sequences: Higher-order polynomial sequences where the leading term is of degree 3.
- Finite Differences: If you calculate the differences between consecutive terms in the sequence, a cubic sequence will have constant second differences.
If you can describe the sequences or provide the actual numerical values, I could help determine which one can be approximated by \(4n^3\). Please share the specific sequences!
