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
