Logical Question:

Answer #1
1 11 21 1211 111221 next element (2211111112)

lets see how ....

First we will ignore 1 and 11

taking 11 and 21 ... keep 11 at last = __11 and then reverse 21 as 12 and keep first we will get 1211.

moving further pick last 2 number as 21 and 1211 ...... follow same procedure keep first number in last = ....21 and now 1211 will change to 1112 ...... and keep in front 111221

next number will be

taking 1112 and 111221 as previous 2 number

......1112
2211111112 (answer) next in the sequence

Answer #2
The Next number would 312211.
Here\\'s how
First the number is 1.
Next it is 1 time 1 so 11
Next it is 2 times 1 so 21
Next it is 1 time 2 and 1 time 1, so 1211
Next it is 1 time 1 and 1 time 2 and 2 time 1, so 111221
So probably next one would be ; 3 time 1 and 2 time 2 and 1 time 1, so 312211

Answer #3
1 = One 1 (11),
11= Two 1 (21),
21= One 2, One 1 (1211),
1211= One 1, One 2, Two 1 (111221),
So the next element will be 312211.
