We get the next term by describing the previous one
and saying it.
for.eg. 2 implies 'one' 2 so 12
12 implies 'one' 1 and 'one' 2 so 1112
1112 implies 'three' 1 and 'one' 2 so 3112.
Hence the answer is describing 1113122112 i.e.
311311222112 option no. 5

The term describes the previous
term. Say the numbers out loud:
2 < - Is One "2" : 12
12 < - Is One "1" and One "2" :
1112
1112 < - Three "1" and One "2" : 3112
3112 < - One "3" Two "1" and One
"2" : 132112 So now you can describe the last
one :
132112 < - One "1" One "3" One
"2" Two "1" and One "2" :

answer : 311311222112
the problem depends up on number of occurence of every digit in the number.
1st term 2,
next term 2 occurs 1 time . therefore 1 time of 2= 12 (2nd term)
next term
1 occurs 1 time 2 occurs one time therefore 1 time of 1 and 1 time of 2=1112
by solving the 1113122112
=3 times of 1 &1 time of 3&1time of 1 &2 times of 2& 2 times of 1 and 1 time of 2 we get
311311222112(answer)

The term describes the previous term. Say the numbers out loud:
2 = One 2 = 12
12 = One 1 One 2 = 1112
1112 = Three 1 One 2 = 3112
3112 = One 3 Two 1 One 2 = 132112
132112 = One 1 One 3 One 2 Two 1 One 2 = 1113122112
Similarly,
1113122112 = Three 1 One 3 One 1 Two 2 Two One One 2 = 311311222112 Answer

2 -> two
12 -> one '2'
1112 -> one '1' one '2'
like...
1113122112 -> three '1' one '3' one '1' two '2' two '1' one '2'

IFFAT IRAM   10 years AGO

this series has the no.s preceded by their count
1'st no. = 2
since first no. has one 2
so 2nd no. will be 12
now, 2nd no. have one 1 and one 2
so, 3rd no. = 1112
proceeding like this the required no. is
three 1 one 3 one 1 two 2 two 1 one 2

Ans: 311311222112 Option(5)
The nth term in this series is the description of the number of digits in the (n-1)th term.
1st term is 2
2nd term explains 1st term: one two i.e; 12
3rd term explains 2nd term: one one one two i.e; 1122
last given term is 1113122112 = (111 3 1 22 11 2) explained as three ones, one three, one one, two two\'s, two one\'s and one two. Hence answer is 311311222112

12= one 2

3112= three 1 one 2

Bagmita Chanda   10 years AGO

2 => 1 no. of 2
so next term is 12
now 12 => 1 no. of 1 & 1 no. of 2
so next term is 1112
now again 1112 => 3 no.s of 1 & 1 no. of 2
so the next term is 3112
like this from 1113122112 we get 3 no.s of 1 then 1 no. of 3 then 1 no. of 1 then 2 no.s of 2 then 2 no.s of 1 and 1 no. of 2 implies 311311222112 as the next no. in the series
