Beyond the Answer
To find the limit of the sequence \( \left\{\frac{4^{5n}}{n!}\right\} \), we can use the Growth Rates of Sequences Theorem. As \( n \) approaches infinity, we note that \( n! \) grows much faster than \( 4^{5n} \). In fact, while \( 4^{5n} \) represents exponential growth, \( n! \) reflects factorial growth, which outpaces exponential functions. Therefore, A. The limit of the sequence is \( 0 \).
