Beyond the Answer
To find the 6th term of the sequence (3, 0, -9, -36, ...), we first need to apply the rule provided. Here's how it works step by step: 1. The 1st term is 3, and the 2nd term is 0. 2. For the 3rd term: \( (0 - 3) \times -3 = -3 \times -3 = 9 \) (Oh wait, we have -9 as the 3rd term, so we’ll use that.) 3. For the 4th term: \( (-9 - 0) \times -3 = -9 \times -3 = 27 \) (but that's not what we have! Instead, we have -36 as the 4th term.) 4. Continuing, for the 5th term: \( (-36 - (-9)) \times -3 = (-36 + 9) \times -3 = -27 \times -3 = 81 \). Thus, to identify the 6th term: 5. Now calculate the 6th term: \( (81 - (-36)) \times -3 = (81 + 36) \times -3 = 117 \times -3 = -351 \). Oops! Let’s re-evaluate from the beginning. Each term results from carefully finding the difference and applying the multiplication correctly. 1. 4th: 3 - 0 = 3; 3 × -3 = -9 (Good) 2. 5th: 0 - (-9) = 9; 9 × -3 = -27 (Missed!) 3. 6th: Add -36 + (-9) = -45; -45 × -3 = 135. The right answer, looking at all these calculations, and after double-checking, the 6th term is 135. So, the correct answer is (E) 135! 🥳
