Answer :
Final answer:
The given sequence is a geometric sequence with a common ratio of 1.25. The nth term of the sequence can be found using the formula an = a1 * r^(n-1), where a1 is the first term and r is the common ratio.
Explanation:
The given sequence is a geometric sequence. A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a constant ratio. In this case, the first term is 4 and the common ratio is 1.25 (since each term is obtained by multiplying the previous term by 1.25). Therefore, the nth term of the sequence can be found using the formula: an = a1 * r^(n-1).
Plugging in the given values, we have: an = 4 * 1.25^(n-1). So, to find any term in the sequence, you can use this formula.
