Step 15: 9828 + 702 = 10530
Step 16: 10530 + 702 = 11232
Step 17: 11232 + 702 = 11934
Step 18: 11934 + 702 = 12636
Step 19: 12636 + 702 = 13338
Step 20: 13338 + 702 = 14040
Step 21: 14040 + 702 = 14742
Step 22: 14742 + 702 = 15444
Step 23: 15444 + 702 = 16146
Step 24: 16146 + 702 = 16848
Step 25: 16848 + 702 = 17550
Step 26: 17550 + 702 = 18252
Step 27: 18252 + 702 = 18954
Step 28: 18954 + 702 = 19656
Step 29: 19656 + 702 = 20358
Step 30: 20358 + 702 = 21060
Step 31: 21060 + 702 = 21762
Step 32: 21762 + 702 = 22464
Step 33: 22464 + 702 = 23166
Step 34: 23166 + 702 = 23868
Step 35: 23868 + 702 = 24570
Step 36: 24570 + 702 = 25272
Step 37: 25272 + 702 = 25974
Step 38: 25974 + 702 = 26676
Step 39: 26676 + 702 = 27378
Step 40: 27378 + 702 = 28080
Step 41: 28080 + 702 = 28782
Step 42: 28782 + 702 = 29484
Step 43: 29484 + 702 = 30186
