what is the pattern when multipled by 4 gives answer which is equal to shifting the previous numbber to left and adding 4 to right and still maintain the number of digits(like remove the leftmost digit) ???

next question :
there is an interesting number whose units place digit is "6"
and when the number is multiplied by "4",the product will be the number obtained by shifting every digit of the previuos (our number) to right side by one unit and the left most digit will become "6" (our previous right most digit)??
whats the number???
