1. **Problem:** Find the next term in the series: 147, E53, A63, W77, S95, ? 2. **Formula/Approach:** Analyze the pattern separately for the numeric and alphabetic parts. 3. **Step 1:** Numeric pattern: 147, 53, 63, 77, 95 - Check differences: 53 - 147 = -94 (seems off, so consider only last two digits or separate analysis) - Look at last two digits: 47, 53, 63, 77, 95 - Differences: 53-47=6, 63-53=10, 77-63=14, 95-77=18 - Differences increase by 4 each time: 6, 10, 14, 18, next difference = 22 - Next number last two digits: 95 + 22 = 117 4. **Step 2:** Alphabetic pattern: E, A, W, S, ? - Convert letters to positions: E=5, A=1, W=23, S=19 - Differences: 1-5=-4, 23-1=22, 19-23=-4 - Pattern alternates between -4 and +22 - Next difference should be +22: 19 + 22 = 41 - Since alphabet has 26 letters, 41 - 26 = 15, which corresponds to O 5. **Step 3:** Combine alphabet and number: O117 6. **Answer:** Option C. O117 Final answer: **O117**
