Question

One of the numbers in the given options does not belong to the group.

$23,-1,14,33,47$

• A. $23$
• B. $-1$
• C. $14$
• D. $33$

Answer 1

The correct option is D $33$

All other numbers except $33$ are of the form $n^2-2$.
Option A: n = $5$ ($5^2-2=23$)
Option B: n = $1$ ($1^2-2=-3$)
Option C: n = $4$ ($4^2-2=14$)

Option D doesn't follow this rule.
