Step 34: 15741 + 477 = 16218
Step 35: 16218 + 477 = 16695
Step 36: 16695 + 477 = 17172
Step 37: 17172 + 477 = 17649
Step 38: 17649 + 477 = 18126
Step 39: 18126 + 477 = 18603
Step 40: 18603 + 477 = 19080
Step 41: 19080 + 477 = 19557
Step 42: 19557 + 477 = 20034
Step 43: 20034 + 477 = 20511
Step 44: 20511 + 477 = 20988
Step 45: 20988 + 477 = 21465
Step 46: 21465 + 477 = 21942
Step 47: 21942 + 477 = 22419
Step 48: 22419 + 477 = 22896
Step 49: 22896 + 477 = 23373
Step 50: 23373 + 477 = 23850
Step 51: 23850 + 477 = 24327
Step 52: 24327 + 477 = 24804
