Find out the wrong number 10, 14, 28, 32, 64, 68, 132

Option d: 132. Solution: Let's analyze the sequence of operations between consecutive terms: - 10 +4 14 - 14 × 2 28 - 28 +4 32 - 32 × 2 64 - 64 +4 68 - Following the alternating pattern of +4, × 2, +4, × 2, +4, × 2 , the next term should be: 68 × 2 = 136 The series lists 132 instead of 136 . Therefore, 132 is the wrong term in the series. Hence, Option D is the correct answer.

Find out the wrong number $10, 14, 28, 32, 64, 68, 132$

The correct answer is Option d: $132$. Let's analyze the sequence of operations between consecutive terms: - $10 \xrightarrow{+4} 14$ - $14 \xrightarrow{\times 2} 28$ - $28 \xrightarrow{+4} 32$ - $32 \xrightarrow{\times 2} 64$ - $64 \xrightarrow{+4} 68$ - Following the alternating pattern of $+4, \times 2, +4, \times 2, +4, \times 2$, the next term should be: $$68 \times 2 = 136$$ The series lists $132$ instead of $136$. Therefore, $132$ is the wrong term in the series. Hence, **Option D** is the correct answer.

Correct Answer

✅ Option d — $\displaystyle 132$

All Options:

A $\displaystyle 28$
B $\displaystyle 32$
C $\displaystyle 64$
D $\displaystyle 132$

Detailed Solution & Explanation

Let's analyze the sequence of operations between consecutive terms:
-

\displaystyle 10 \xrightarrow{+4} 14

\displaystyle 14 \xrightarrow{\times 2} 28

\displaystyle 28 \xrightarrow{+4} 32

\displaystyle 32 \xrightarrow{\times 2} 64

\displaystyle 64 \xrightarrow{+4} 68

- Following the alternating pattern of

\displaystyle +4, \times 2, +4, \times 2, +4, \times 2

, the next term should be:

68 \times 2 = 136

The series lists

\displaystyle 132

instead of

\displaystyle 136

. Therefore,

\displaystyle 132

is the wrong term in the series.

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