Step 35: 8330 + 245 = 8575
Step 36: 8575 + 245 = 8820
Step 37: 8820 + 245 = 9065
Step 38: 9065 + 245 = 9310
Step 39: 9310 + 245 = 9555
Step 40: 9555 + 245 = 9800
Step 41: 9800 + 245 = 10045
Step 42: 10045 + 245 = 10290
Step 43: 10290 + 245 = 10535
Step 44: 10535 + 245 = 10780
Step 45: 10780 + 245 = 11025
Step 46: 11025 + 245 = 11270
Step 47: 11270 + 245 = 11515
Step 48: 11515 + 245 = 11760
Step 49: 11760 + 245 = 12005
Step 50: 12005 + 245 = 12250
Step 51: 12250 + 245 = 12495
Step 52: 12495 + 245 = 12740
