• 1) ''-192''. First four in one pack('4'*-2='-8', '2'*-2='-4'),next four ('32'*-6='-192', '26'*-6='-156').
  2)"21". (x, 2x, 2x-1), 3 in a pack.
  3)"24". Two packs i.e left n right and 3 in each pack . For left pack(x, 3x, 3+x), right pack(x, 3+x, 3x).
  4)"72". Subtract with primes(-2, -3, -5, -7, -11...)
  5)"6". Consider '2's position, it is fixed on 3, 6, 9, 12. Now check the next value i.e 4th table positions(4, 8, 12, 16), we have 0, 2, 4 and the next will be 6.
  6)"(109/6)"Consider the pairs and the difference of the results in each pair after division will be in increment of 1. Like (2/3 = 0.6, 5/3=1.6), the difference of their results is 1, similarly the difference of result of next pair will be 2 and so on.
  7)"156". 4 as a pair ( x, x+11, x+23, y=x+10), (y, y+11, y+33, z=y+10), (z, z+11, z+63, w=z+10), (w, w+11, w+113, q=w+10). Here, observe the third term in a pair, we have addition of 23, 33, 63. This is our series, so the diff is 10, 30. Obviously the next one will be 50. So adding 50 to 63 we get 113.
  8)"125". Consider even terms, i.e 16 multiples. 16, 16*4 +4, 16*5 + 4 +3, 16*6 + 7 +3, 16*7 + 10+3.
  9)Didn't get the answer.
