The logic follows here is:

The next number in the column is obtained by multiplying by 3 from the previous number.

I COLOUMN →

  • 2 × 3 = 6
  • × 3 = 18
  • 18 × 3 = 54

II COLOUMN →

  • 4 × 3 = 12
  • 12 × 3 = 36
  • 36 × 3 = 108

III COLOUMN →

  • 1 × 3 = 3
  • 3 × 3 = 9
  • 9 × 3 = 27

IV COLOUMN →

  • 5 × 3 = 15
  • 15 × 3 = 45
  • 45 × 3 = 135 ≠ 100

Thus, the wrong term is "100".

Hence, the correct answer is "100".
