Explanation

Pattern: multiply and add. 125×2+5=255, 255×3+25=790, 790×4+145=3285, 3285×5+745=17050, 17050×6+4725=104525. The added numbers increase: 5, 25, 145, 745, 4725. But 255×3+25=790, 255×3=765+25=790. So 255 fits. Let me verify: Actually 255 is correct per pattern. Wait - 255 should be 255×2+5=515, not 255. So 255 is wrong.
