Step 25: 3792 + 158 = 3950
Step 26: 3950 + 158 = 4108
Step 27: 4108 + 158 = 4266
Step 28: 4266 + 158 = 4424
Step 29: 4424 + 158 = 4582
Step 30: 4582 + 158 = 4740
Step 31: 4740 + 158 = 4898
Step 32: 4898 + 158 = 5056
Step 33: 5056 + 158 = 5214
Step 34: 5214 + 158 = 5372
Step 35: 5372 + 158 = 5530
Step 36: 5530 + 158 = 5688
Step 37: 5688 + 158 = 5846
Step 38: 5846 + 158 = 6004
Step 39: 6004 + 158 = 6162
Step 40: 6162 + 158 = 6320
Step 41: 6320 + 158 = 6478
Step 42: 6478 + 158 = 6636
Step 43: 6636 + 158 = 6794
Step 44: 6794 + 158 = 6952
Step 45: 6952 + 158 = 7110
