Step 22: 18690 + 890 = 19580
Step 23: 19580 + 890 = 20470
Step 24: 20470 + 890 = 21360
Step 25: 21360 + 890 = 22250
Step 26: 22250 + 890 = 23140
Step 27: 23140 + 890 = 24030
Step 28: 24030 + 890 = 24920
Step 29: 24920 + 890 = 25810
Step 30: 25810 + 890 = 26700
Step 31: 26700 + 890 = 27590
Step 32: 27590 + 890 = 28480
Step 33: 28480 + 890 = 29370
Step 34: 29370 + 890 = 30260
Step 35: 30260 + 890 = 31150
Step 36: 31150 + 890 = 32040
Step 37: 32040 + 890 = 32930
Step 38: 32930 + 890 = 33820
Step 39: 33820 + 890 = 34710
Step 40: 34710 + 890 = 35600
Step 41: 35600 + 890 = 36490
Step 42: 36490 + 890 = 37380
Step 43: 37380 + 890 = 38270
Step 44: 38270 + 890 = 39160
Step 45: 39160 + 890 = 40050
Step 46: 40050 + 890 = 40940
Step 47: 40940 + 890 = 41830
Step 48: 41830 + 890 = 42720
Step 49: 42720 + 890 = 43610
