⟩ Here is a sequence of numbers 1 11 21 1211 111221 It seems to be a strange sequence, but yet there is a system behind it... What is the next term in this sequence?
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
