Each number (besides the initial one) describes the number before it like this:
1
one 1 (11)
two 1's (21)
one 2 and one 1 (1211)
one 1, one 2 and two 1's (111221)
three 1's, two 2's and one 1 (312211)
and so on...

The method to answering this is:
1 this is one one -> 1 1
11 this is two ones -> 2 1
2 1 this is one two and one one -> 1 2 1 1
1 2 1 1 this is one one, one two and two ones
1 1 1 2 2 1

This is just saying that in the previous number there are:
3 1's followed by 1 3 followed by 1 1 followed by 2 2's etc

The seventh line is wrong, so the question is pointless.
