Question

1, 3/5, 9/25 Find the 8th term.

Answer 1

Answer:

Step-by-step explanation:

This is a geometric sequence.

a = first term = 1

Common ratio = r = second term ÷ first term

                        = (3/5)÷ 1 = 3/5

$t_{n}=ar^{n-1}\\\\t_{8}=1*(\dfrac{3}{5})^{7}\\\\= \dfrac{3^{7}}{5^{7}}\\\\\\= \dfrac{2187}{78125}$
