Series and Odd Man out Practice Test 1

Concept:Find the term that breaks the pattern in the given series.Explanation:The series follows the rule: multiply the previous term by $4$ and then add $2$.Check from the first term: $2 \times 4 + 2 = 10$, not $12$.Using the correct value $10$, the next terms become: $10 \times 4 + 2 = 42$.Then, $42 \times 4 + 2 = 170$.Finally, $170 \times 4 + 2 = 682$.So, the correct series should be $2, 10, 42, 170, 682$.Therefore, $12$ is the wrong term and should be replaced by $10$.Answer:The odd term is $12$ (Option C).
