The last number consists of one 3 followed by one 1 followed by two 2s followed by two 1s Stringing all these numbers together gives 13112221
13112221 1 time 3, 1 time 1, 2 times 2, 2 times 1. and the next would be 1 time 1, 1 time 3, 2 times 1, 3 times 2, 1 time 1 1113213211 and so on.
111221
Any answer would work, but the most 'obvious' answer is 111221. To see why, try reading the numbers out loud one digit at a time.
