Step 14: 7774 + 598 = 8372
Step 15: 8372 + 598 = 8970
Step 16: 8970 + 598 = 9568
Step 17: 9568 + 598 = 10166
Step 18: 10166 + 598 = 10764
Step 19: 10764 + 598 = 11362
Step 20: 11362 + 598 = 11960
Step 21: 11960 + 598 = 12558
Step 22: 12558 + 598 = 13156
Step 23: 13156 + 598 = 13754
Step 24: 13754 + 598 = 14352
Step 25: 14352 + 598 = 14950
Step 26: 14950 + 598 = 15548
Step 27: 15548 + 598 = 16146
Step 28: 16146 + 598 = 16744
Step 29: 16744 + 598 = 17342
Step 30: 17342 + 598 = 17940
Step 31: 17940 + 598 = 18538
Step 32: 18538 + 598 = 19136
Step 33: 19136 + 598 = 19734
Step 34: 19734 + 598 = 20332
Step 35: 20332 + 598 = 20930
Step 36: 20930 + 598 = 21528
Step 37: 21528 + 598 = 22126
Step 38: 22126 + 598 = 22724
Step 39: 22724 + 598 = 23322
Step 40: 23322 + 598 = 23920
Step 41: 23920 + 598 = 24518
Step 42: 24518 + 598 = 25116
Step 43: 25116 + 598 = 25714
