Multiply the prev no by 4 and add (join) the prev result digits at the end
1,
1*4=4"1"--> 1 is the prev digit
41*4=164"41"--> 41 is the prev digit
16441*4=65764"16441"--> 16441 is the prev digit
6576416441*4=26305665764"6576416441" is the prev digit
So Option 1..

According to the question
the 2nd number has two parts
1st part is the number multiple by 4
2nd part is the number itself
example:-
1
next number
1st part = 1*4 = 4
2nd part = 1
so the next number after 1 is 41
like this way we get our appropriate result .
that's it.
Option 1.

1 st number is 1
then multiply 1 with 4 and write it before 1
so, it will be 41,which is the 2nd number of the series.
then multiply 41 with 4 and write it before 41
so,it will be 16441, which is the 3rd number of the series.
then multiply 16441 with 4 and write it before 16441
so,it will be 6576416441, which is the 4th number of the series.
then multiply 6576416441 with 4 and write it before 6576416441
