1 Identify the pattern for the following sequence. Find the next three terms in the sequence. I \( -1,3,-9,27 \), a. Multiply by \( 3 ; 81,243,729 \) b. Multiply by \( -3 ;-81,243,-729 \) c. Multiply by \( -3 ; 81,243,729 \) d. Multiply by \( 3 ;-81,-243,-729 \)

To identify the pattern in the sequence \(-1, 3, -9, 27\) and determine the next three terms, let's analyze the progression: 1. **Identify the Pattern:** - Starting with \(-1\): - \(3 = (-1) \times (-3)\) - \(-9 = 3 \times (-3)\) - \(27 = (-9) \times (-3)\) The pattern involves **multiplying by \(-3\)** each time. 2. **Determine the Next Three Terms:** - \(27 \times (-3) = -81\) - \(-81 \times (-3) = 243\) - \(243 \times (-3) = -729\) Therefore, the next three terms are \(-81, 243, -729\). 3. **Choose the Correct Option:** - **Option b** states: "Multiply by \(-3\); \(-81, 243, -729\)", which matches our findings. **Answer:** **b. Multiply by \( -3 \); \(-81,243,-729 \)**
