Identify the pattern for the following sequence. Find the next three terms in the sequence.-1, 3, -9, 27, ____, ____, ____,...

Each term is found by multiplying the previous term by -3: -1 × -3 = 3, 3 × -3 = -9, and -9 × -3 = 27. Continuing gives 27 × -3 = -81, then -81 × -3 = 243, and 243 × -3 = -729. The correct choice is “Multiply by -3; -81, 243, -729.”
