Step 16: 10830 + 722 = 11552
Step 17: 11552 + 722 = 12274
Step 18: 12274 + 722 = 12996
Step 19: 12996 + 722 = 13718
Step 20: 13718 + 722 = 14440
Step 21: 14440 + 722 = 15162
Step 22: 15162 + 722 = 15884
Step 23: 15884 + 722 = 16606
Step 24: 16606 + 722 = 17328
Step 25: 17328 + 722 = 18050
Step 26: 18050 + 722 = 18772
Step 27: 18772 + 722 = 19494
Step 28: 19494 + 722 = 20216
Step 29: 20216 + 722 = 20938
Step 30: 20938 + 722 = 21660
Step 31: 21660 + 722 = 22382
Step 32: 22382 + 722 = 23104
Step 33: 23104 + 722 = 23826
Step 34: 23826 + 722 = 24548
Step 35: 24548 + 722 = 25270
Step 36: 25270 + 722 = 25992
Step 37: 25992 + 722 = 26714
Step 38: 26714 + 722 = 27436
Step 39: 27436 + 722 = 28158
Step 40: 28158 + 722 = 28880
Step 41: 28880 + 722 = 29602
Step 42: 29602 + 722 = 30324
Step 43: 30324 + 722 = 31046
