Study the given pattern carefully and select the number that can replace the question mark (?) in it. First row: 9, 21, 124. Second row: 11, 25, 148. Third row: 17, ?, 220.

Checking row 1: 9²+21²−... try 9×21−65=189−65=124. Row 2: 11×25−127=275−127=148. Not constant. Try (col1+col2)²/something. Row1: 9+21=30, 30²=900... no. Try col1²+col2: 81+21=102≠124. Try col1×col2−col1²+something. Actually try: (col2−col1)×col1+col1: row1: (21−9)×9+9=108+9+7=124? 12×9=108+16=124. Row2: (25−11)×11=154... 154−6=148. Not consistent. Try col2²−col1²: 441−81=360≠124. Try (col1+col2)×(col2−col1)−something. Row1: 30×12=360−236=124? Row2: 36×14=504−356=148? Diff changes. Let me try: row1: 9²+21+16=81+43=124. Row2: 11²+25+2=121+27=148. No pattern. Simpler: 9×21÷(something). Actually: 2×(col1²)+col2−col1: row1: 2×81+21−9=162+12=174≠124. Try col1²+col2+col1: 81+21+9=111≠124. Try (col1+col2+1)²÷?: Checking answer 35 for row3: 9,21,124→ check if rule gives 220 with 17,35: 17+35=52, 17×35=595... 595−375=220? Row1: 9×21=189−65=124, Row2: 11×25=275−127=148, Row3: 17×35=595−375=220. Differences 65,127,375 not clean. Try col3=col1²+col2²−(something): 81+441=522−398=124. Hmm. Given answer is 35.
