Explanation

Check pattern: 200 + 1×10 = 210, 210 + 2×7 = 224, 224 + 3×12 = 260. For 260: should add 4×(difference pattern). The pattern of additions is 10, 14, 36, 62, 182. These don't form a consistent sequence. Alternative: 200×1.05=210, 210×1.067≈224, 224×1.161≈260, 260×1.238≈322. 322×1.565≈504. The growth pattern accelerates; 260 doesn't fit the squared difference pattern that should give 262.
