Question

Q) What is the next number in the series 01, 1011, 111021, 31101211…… ?

Answer 1

01 - First number in the series.

1011 - Second number in the series. This describes the two digits in the first number series (""01"") -- first digit is ""0"", so it means that there is one (1) zero (0); and second digit is ""1"", which means that there is one (1) one (1). Thus, 1011.

Since you've noticed that we are only describing the preceding number series, then the last number that will be described is ""31101211"" -- first digit is ""3"", which means that there is one (1) three (3); second & third digits are ""1"", which means that there are two (2) ones (1); fourth digit is ""0"", which means that there is one (1) zero (0); fifth digit is ""1"", which means that there is one (1) one (1); sixth digit is ""2"", which means that there is one (1) two (2); and the last two digits are ""1"", which means that there are two (2) ones (1). Thus, 132110111221.
