Answer:
-4860
Explanation:
The formula for finding the nth term (An) of a geometric sequence is;
An = a₁ * r^(n-1)
where a₁ is the first term, r is the common ratio, and n is the number of terms.
Plugging in the given values, we have;
An = 20 * (-3)^(6-1)
An = 20 * (-3)^5
An = 20 * (-243)
An = -4860
Therefore, the answer is (Ob) -4860
