Question

In the following series, find the incorrect number.

$4,9,16,25,34.$

• A. $4$
• B. $16$
• C. $34$
• D. $9$

Answer 1

Answer: (C)

$34$

In this series, it is series of square of whole number in increasing order,

$2^2$$=4$

$3^2$$=9$

$4^2$$=16$

$5^2$$=25$

Next term would be $6^2$$=36$

Thus, $34$ is a wrong number.
