Answer 2

Answer:

The odd man out is 64.

Step-by-step explanation:

Odd man out:

In odd man out problems all the items given in the question except one follow a certain pattern or a group. The item which is different and doesn't belong to that group will be the answer. Problems of this type are categorized under the head of CLASSIFICATION.

Given sequence is :

64 125 216 and 343

64 = 4³ and 8²

125 = 5³

216 = 6³

343 = 7³

As we can see that 125, 216 and 343 are only the cubes of any number whereas 64 is cube as well as the square of numbers, so it does not follow the rule that other three ( 125, 216 , 343) follows.

Hence 64 is the odd one out in the sequence.
