Question

Pick the odd one out:

$86,52,28,13,5,2$

• A. $28$
• B. $52$
• C. $13$
• D. $86$

Answer 1

Answer: (D)

$86$

Series moves from the right end with a difference of $0,3,8,15,24,35$ i.e., with a difference of number, which are one less than the square of successive natural number.
$5-2=3$
$13-5=8$
..........
...........
$86-52=34$.

This difference does not follow the pattern in the series.
So, option D is the correct answer.
