Step 37: 4932 + 137 = 5069
Step 38: 5069 + 137 = 5206
Step 39: 5206 + 137 = 5343
Step 40: 5343 + 137 = 5480
Step 41: 5480 + 137 = 5617
Step 42: 5617 + 137 = 5754
Step 43: 5754 + 137 = 5891
Step 44: 5891 + 137 = 6028
Step 45: 6028 + 137 = 6165
Step 46: 6165 + 137 = 6302
Step 47: 6302 + 137 = 6439
Step 48: 6439 + 137 = 6576
Step 49: 6576 + 137 = 6713
Step 50: 6713 + 137 = 6850
