Question

One of the numbers does not belong to the group. Identify the number.

$14,39,84,155,260$

• A. $14$
• B. $39$
• C. $84$
• D. $260$

Answer 1

Answer: (D)

$260$

All options follow this trend of $14=2+2^2+2^3,3+3^2+3^3,$ $84=4+4^2+4^3$ and so on.
But $260\ne 6+6^2+6^3$ it is equal to $248$

So option D is the odd one.
