Question

Find out the wrong number in the series given below:
 \[ 10, 14, 28, 32, 64, 68, 132 \]

• A. 132
• B. 64
• C. 32
• D. 28

Hint:

In number series problems, look for patterns such as addition, subtraction, multiplication, or division, and how each number is related to the next.

Answer 1

The Correct Option is A

The series follows the pattern: \[ 10, 14, 28, 32, 64, 68, 132 \] By analyzing the pattern, we can observe that the series doubles each number and then alternates between adding or subtracting a fixed number. The number 132 does not fit with the rest of the series, as it breaks this pattern. Thus, 132 is the wrong number.

Answer 2

Given the series: 10, 14, 28, 32, 64, 68, 132

Let's analyze the pattern:
- 10 → 14: +4
- 14 → 28: ×2
- 28 → 32: +4
- 32 → 64: ×2
- 64 → 68: +4
- 68 → 132: This should ideally be ×2, which equals 136, but here it is 132.

The pattern alternates between adding 4 and multiplying by 2.
According to this pattern, after 68, the next number should be:
68 × 2 = 136, not 132.

Therefore, the wrong number in the series is 132.

Conclusion:
The incorrect number in the series is 132.
