✅ Option d — 132\displaystyle 132

All Options:

  • A28\displaystyle 28
  • B32\displaystyle 32
  • C64\displaystyle 64
  • D132\displaystyle 132

Detailed Solution & Explanation

Let's analyze the sequence of operations between consecutive terms:
- 10→+414\displaystyle 10 \xrightarrow{+4} 14
- 14→×228\displaystyle 14 \xrightarrow{\times 2} 28
- 28→+432\displaystyle 28 \xrightarrow{+4} 32
- 32→×264\displaystyle 32 \xrightarrow{\times 2} 64
- 64→+468\displaystyle 64 \xrightarrow{+4} 68
- Following the alternating pattern of +4,×2,+4,×2,+4,×2\displaystyle +4, \times 2, +4, \times 2, +4, \times 2, the next term should be:
68×2=13668 \times 2 = 136
The series lists 132\displaystyle 132 instead of 136\displaystyle 136. Therefore, 132\displaystyle 132 is the wrong term in the series.

Hence, **Option D** is the correct answer.
