Question

1
11
21
1211
111221
312211
13112221

This will take some time to think, but it can be done!!

Answer 1

I have to say that the answer is 1113213211

Row one is one 1

Row 2 describes what is in row one (there is "1" "1")

Row 3 describes what is in row tow ( there are "2" "1")

THe same goes on for all the rows...so following row 7...(13112221)

the answer is 1113213211....there is "1" "1"...then there is "1" "3"....then there are "2" "1"s....then there are "3" "2"'s....and then there is "1" "1" left...confusing yes, but none the less describing what is shown in the previous line using numbers only

Answer 2
