The correct Answer is:
To find the sum of the product of the corresponding terms of the sequences \(2, 4, 8, 16, 32\) and \(128, 32, 8, 2, \frac{1}{2}\), we will follow these steps: ### Step 1: Identify the corresponding terms The two sequences are: - First sequence: \(2, 4, 8, 16, 32\) - Second sequence: \(128, 32, 8, 2, \frac{1}{2}\) We will pair the corresponding terms: - First term: \(2\) and \(128\) - Second term: \(4\) and \(32\) - Third term: \(8\) and \(8\) - Fourth term: \(16\) and \(2\) - Fifth term: \(32\) and \(\frac{1}{2}\) ### Step 2: Calculate the products of the corresponding terms Now we will calculate the product of each pair: 1. \(2 \times 128 = 256\) 2. \(4 \times 32 = 128\) 3. \(8 \times 8 = 64\) 4. \(16 \times 2 = 32\) 5. \(32 \times \frac{1}{2} = 16\) ### Step 3: Sum the products Now, we will sum all the products calculated in the previous step: \[ 256 + 128 + 64 + 32 + 16 \] ### Step 4: Perform the addition Calculating the sum step-by-step: 1. \(256 + 128 = 384\) 2. \(384 + 64 = 448\) 3. \(448 + 32 = 480\) 4. \(480 + 16 = 496\) Thus, the final sum of the products is: \[ \text{Sum} = 496 \] ### Final Answer The sum of the product of the corresponding terms of the sequences is \(496\). ---
