Find the wrong term in the series given below:
3, 12, 36, 144, 432, 1738, 5184
Solution:
Let us examine the pattern in the series:
3 × 4 = 12
12 × 3 = 36
36 × 4 = 144
144 × 3 = 432
432 × 4 = 1728, but the given number is 1738, which is incorrect
1728 × 3 = 5184, which matches the last number
So, the correct pattern is alternating multiplication by 4 and 3. The number 1738 does not follow this pattern and is 10 more than expected.
Answer: Option C (1738) is the wrong term.
