Logic : (2nd number - 1st number) = (3rd number - 2nd number)

​So,

  • Option - (1) : (90 –93 –96)

93 - 90 = 96 - 93

3 = 3 (LHS = RHS)​

  • Option - (2) : (84 –87 –90)

87 - 84 = 90 - 87

3 = 3 (LHS = RHS)

  • Option - (3) : (44 –49 –52)

49 - 44 = 52 - 49

5 ≠ 3 (LHS ≠ RHS)

  • Option - (4) : (58 –61 –64)

61 - 58 = 64 - 61

3 = 3 (LHS = RHS)

Hence, "Option - (3)" is the correct answer.
