Step 40: 5070 + 130 = 5200
Step 41: 5200 + 130 = 5330
Step 42: 5330 + 130 = 5460
Step 43: 5460 + 130 = 5590
Step 44: 5590 + 130 = 5720
Step 45: 5720 + 130 = 5850
Step 46: 5850 + 130 = 5980
Step 47: 5980 + 130 = 6110
Step 48: 6110 + 130 = 6240
Step 49: 6240 + 130 = 6370
Step 50: 6370 + 130 = 6500
Step 51: 6500 + 130 = 6630
Step 52: 6630 + 130 = 6760
Step 53: 6760 + 130 = 6890
Step 54: 6890 + 130 = 7020
Step 55: 7020 + 130 = 7150
Step 56: 7150 + 130 = 7280
Step 57: 7280 + 130 = 7410
Step 58: 7410 + 130 = 7540
Step 59: 7540 + 130 = 7670
Step 60: 7670 + 130 = 7800
Step 61: 7800 + 130 = 7930
Step 62: 7930 + 130 = 8060
Step 63: 8060 + 130 = 8190
Step 64: 8190 + 130 = 8320
Step 65: 8320 + 130 = 8450
Step 66: 8450 + 130 = 8580
