Question

Identify the wrong term in the given series.

$9,15,24,34,51,69,90$.

• A. $15$
• B. $24$
• C. $34$
• D. $51$

Answer 1

Answer: (C)

$34$

The difference between the consecutive numbers is increasing in the multiples of $3$
i.e.
$9,9+6=15,15+9=24,24+12=36,36+15=51,51+18=69,69+21=90$
The fourth term is the wrong term as it should be $36$ and not $34$
Answer is Option C
