Question 6 4 pts Write a formula for the general term (the nth term) of the geometric sequence. 4, 1, \frac{1}{4}, \frac{1}{16}, \frac{1}{64}, ... a_n = 4 \left(\frac{1}{4}\right)^{n-1} a_n = 4 \left(\frac{1}{4}\right)^{n+1} a_n = 4 \left(\frac{1}{4}\right)^n a_n = 4 \left(\frac{1}{16}\right)^{n-1}

Step 1
Identify the common ratio (r) between the terms: To find the common ratio, divide the second term by the first term, or the third term by the second term: r = 16/4 = 4 or 64/16 = 4 Show more…
