Correct Solution: Option C

Step-by-step Solution:

Wrong number in the series: 84

Given series: 56, 58, 62, 70, 84, 118, 182

Differences:

  • 58 − 56 = 2
  • 62 − 58 = 4
  • 70 − 62 = 8
  • 84 − 70 = 14
  • 118 − 84 = 34
  • 182 − 118 = 64

The intended pattern for differences is doubling: 2, 4, 8, 16, 32, 64. Applying this to the series:

  • 56 + 2 = 58
  • 58 + 4 = 62
  • 62 + 8 = 70
  • 70 + 16 = 86
  • 86 + 32 = 118
  • 118 + 64 = 182

Hence the term 84 is incorrect; it should be 86.
