its 1,2,2,3,3,3,4,4,4,4,1,1,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4,4,4,4,1,1,1,2,2,2,2,2,2,..

1,2,2,3,3,3,4,4,4,4 = 10 terms (1st series)
1,1,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4,4,4,4 = 20 terms(2nd series)
1(3times),2(6times),3(9times),4(12times)= 30 terms(3rd series)

Sum of no. of terms= 10+20+30+...+10*n
=10(1+2+3+...+n)
=10*n(n+1)/2 < 2926 => n(n+1)< 585.2 => n less than 24

if n=24,Sum of no. of terms= 10+20+30+...+24*n= 10*24*25/2 = 3000

24th series = [1...(24times),2...(48times),3...(72times),4...(96times)]

i.e there are 96 4's before 3000th term

so, 2926th term =4

=10*n(n+1)/2 < 2926 => n(n+1)< 585.2 => n

ans.4
1,2,2,3,3,3,4,4,4,4=10 terms
1,1,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4,4,4,4=20 terms
10+20+30+............

1st series is=10
2nd=20
3rd=30.....
n(n+1)/2*10
assume to take n=23(nearest of 2926th term)
so,the value=2760.(where n=23)
remaining is 166(2926-2760)
after this i cant solve pls send the valuable solution for this question.the ans for this is 1.
