Step 18: 13175 + 775 = 13950
Step 19: 13950 + 775 = 14725
Step 20: 14725 + 775 = 15500
Step 21: 15500 + 775 = 16275
Step 22: 16275 + 775 = 17050
Step 23: 17050 + 775 = 17825
Step 24: 17825 + 775 = 18600
Step 25: 18600 + 775 = 19375
Step 26: 19375 + 775 = 20150
Step 27: 20150 + 775 = 20925
Step 28: 20925 + 775 = 21700
Step 29: 21700 + 775 = 22475
Step 30: 22475 + 775 = 23250
Step 31: 23250 + 775 = 24025
Step 32: 24025 + 775 = 24800
Step 33: 24800 + 775 = 25575
Step 34: 25575 + 775 = 26350
Step 35: 26350 + 775 = 27125
Step 36: 27125 + 775 = 27900
Step 37: 27900 + 775 = 28675
Step 38: 28675 + 775 = 29450
Step 39: 29450 + 775 = 30225
Step 40: 30225 + 775 = 31000
Step 41: 31000 + 775 = 31775
Step 42: 31775 + 775 = 32550
Step 43: 32550 + 775 = 33325
Step 44: 33325 + 775 = 34100
Step 45: 34100 + 775 = 34875
Step 46: 34875 + 775 = 35650
Step 47: 35650 + 775 = 36425
Step 48: 36425 + 775 = 37200
Step 49: 37200 + 775 = 37975
Step 50: 37975 + 775 = 38750

So, 775*50 = 38750
