The Complete pattern is 85,700, 8,570, 857, 85.7, 8.57, 0.857.It is nothing but just moving the decimal places to the right side.Otherwise each number should multiplied and divided by 10 so that we derived the complete pattern.When you multiply by moving the decimal point to the right, you also need to add a zero to the end of it. This is an alternative method for the pattern.
