Step 4: 1212 + 404 = 1616
Step 5: 1616 + 404 = 2020
Step 6: 2020 + 404 = 2424
Step 7: 2424 + 404 = 2828
Step 8: 2828 + 404 = 3232
Step 9: 3232 + 404 = 3636
Step 10: 3636 + 404 = 4040
Step 11: 4040 + 404 = 4444
Step 12: 4444 + 404 = 4848
Step 13: 4848 + 404 = 5252
Step 14: 5252 + 404 = 5656
Step 15: 5656 + 404 = 6060
Step 16: 6060 + 404 = 6464
Step 17: 6464 + 404 = 6868
Step 18: 6868 + 404 = 7272
Step 19: 7272 + 404 = 7676
Step 20: 7676 + 404 = 8080
Step 21: 8080 + 404 = 8484
Step 22: 8484 + 404 = 8888
Step 23: 8888 + 404 = 9292
Step 24: 9292 + 404 = 9696
Step 25: 9696 + 404 = 10100
Step 26: 10100 + 404 = 10504
Step 27: 10504 + 404 = 10908
Step 28: 10908 + 404 = 11312
Step 29: 11312 + 404 = 11716
Step 30: 11716 + 404 = 12120
Step 31: 12120 + 404 = 12524
Step 32: 12524 + 404 = 12928
Step 33: 12928 + 404 = 13332
Step 34: 13332 + 404 = 13736
Step 35: 13736 + 404 = 14140
Step 36: 14140 + 404 = 14544
Step 37: 14544 + 404 = 14948
Step 38: 14948 + 404 = 15352
Step 39: 15352 + 404 = 15756
Step 40: 15756 + 404 = 16160
Step 41: 16160 + 404 = 16564

So, 404*41 = 16564
