Question

Complete the series by finding out the hidden pattern.
$165,195,255,285,345,?$

• A. $375$
• B. $390$
• C. $420$
• D. $435$
• E. $455$

Answer 1

The correct option is D $435$

Each number of the series is $15$ multiplied by a prime number i.e., $15\times 11,15\times 13,15\times 17,15\times 19,15\times 23,....$
So, the missing term $=15X29=435$
Hence, option (D) is the correct answer.
