1234 => 4 times 12344 => 5 times 123444 => 6 times . . . 4 + 5 + 6 + ...n < 200 n(n+1)/2 - 6 = 200 Solving n = 19 i.e. 4+5+6+...19 = 184 After the 184th term,the sequence has 20 terms 12344444444444444444 = 20 terms => 200th term = 4

Solution:


1234 => 4 times 12344 => 5 times 123444 => 6 times . . . 4 + 5 + 6 + ...n < 200 n(n+1)/2 - 6 = 200 Solving n = 19 i.e. 4+5+6+...19 = 184 After the 184th term,the sequence has 20 terms 12344444444444444444 = 20 terms => 200th term = 4
