a series 1234123441234441234444.....n what is the value on 200th position..??

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

• 1234, 12344, 123444, 1234444, ....
  4, 5, 6, ... or (3 + 1), (3 + 2), (3 + 3), .....n = 3 n+n(n+1)/2
  3 n +n(n+1)/2
