If you get the correct answer, share it with your friends on WhatsApp, Facebook and other social networking sites.

If you look at the series carefully you will figure out the logic between the numbers.

So to get the second number we add 8 to 1;

1 + 8 = 9,

9 + 9 = 18

18 + 10 = 28

So to get the next number in the series;

28 + 11 = 39

Answer = 39.
