    1113213211 ... the sequence is: 1, 11 (or one 1), 21 (two 1's), 1211 (one 2, one 1), etc.

    This series is good one. It describes the number of digits in the previous sequence by just using numbers. So for the last sequence, we have: One 1, One 3, Two 1s, Three 2s and One 1 => 11,13,21,32,11. Hope I didn't miss any.

    1113213211 the numbers describe the previous number.  The first number "1" is described as "one 1" = 11 second "11" is described as "two 1s" = 21 etc...

    I guess it is- 311133211. This time I'm not confident. Looks simple, but difficult to work out!!

    This is an easy one! All it does is count the number of digits from the previous row like this: 1 = start 11 = the previous row had 1 times 1 21 = the previous row had 2 times 1 1211 = the previous row had 1 times 2 followed by 1 times 1 etc. Which means that after 13112221 comes this: 1113213211 = the previous row had 1 times 1 followed by one times 3 follows by 2 times 1 follow by 3 times 2 followed by 1 times 1.
