Multiply each individual digit of a number with \"2\"

12==> 1*2=2, 2*2=4, nd then combine d resul-->24
24==> 2*2=4, 4*2=8 --> 48
48==> 4*2=8, 8*2=16 --> 816
816==> 8*2=16, 1*2=2, 6*2=12 --> 16212
16212==> 1*2=2, 6*2=12, 2*2=4, 1*2=2, 2*2=4 --> 212424

So the next term is 212424

Each number is combination of 2 numbers.Like-
12 is 1 and 2.
24 is 2 and 4.
48 is 4 and 8.
816 is 8 and 16.
16212 is 16 and 212.
Every next number is combination of last number's 2 number and double of 2 number.
So, the next number is 16 and 2*212 i.e. 16424.
so 16424 is answer.
