And as the pattern is followed that is number is divided by 5 so if you divide 1875 by 5 you will get 375.
And if you for the want to check you can divide 375 by 5 you will get 75 then divide 75 by 5 you will get 15 and then again divide 15 by 5 you will get 3 so you can understand that your answer is correct..
