Question

Find out the wrong number in the series given below :
$2,3,5,9,16,33$

• A. $3$
• B. $5$
• C. $9$
• D. $16$

Answer 1

The correct option is D $16$

If we observe, we find that the difference of two consecutive numbers follows the pattern $2^0,2^1,2^2,\dots$
So, $5^{\text{th}}$ number in the series should be $17.$
$\therefore 16$ is wrong.
