Based on the pattern shown in the first two sets, find the missing number in the third set: Set 1: [3, 4, 9] (since 34-2 = 9) Set 2: [25, 2, 81] (since √25 = 5, and 52 = 25; here pattern is: (√First)Second = Third, e.g. 32=9, 92=81, 112=121) Let us re-verify: First column numbers are 3, 25, ?. Second column numbers are 4, 2, 121? No, the layout represents: Row 1: 3, 4, 9 -> 32 = 9 Row 2: 25, 2, 81 -> 92 = 81? Let's look at the grid structure: Column 1 has 3, 25, ?. Column 2 has 4, 2, 121. Column 3 has 9, 81, 2. Pattern: Column 1 value squared or related? √25 = 5. √9 = 3. 32=9. √81=9. 92=81. For row 3: if second element is 121 and third is 2, √121=11. 112=121. So the missing number matching the pattern of square roots in relation is 5.
