Series and Odd Man out Practice Test 7

Concept:The series is built in groups of three, where each group follows the pattern square, number, cube.Explanation:Split the sequence into three groups: $(8,4,64)$, $(36,6,216)$, and $(64,8,512)$.For the second group: $6^2 = 36$, then $6$, then $6^3 = 216$.For the third group: $8^2 = 64$, then $8$, then $8^3 = 512$.So the first group should be: $4^2 = 16$, then $4$, then $4^3 = 64$.But the first term is given as $8$, not $16$.Thus, $8$ is the incorrect term and must be replaced by $16$.Answer:The odd term is $8$.
