Question

In each of the following question, a number series is given with missing of one term. Choose the correct alternative that will continue the same pattern and replace the question mark (?) in the given series.

$122,170,226,290,?$

• A. $289$
• B. $362$
• C. $290$
• D. $325$

Answer 1

Answer: (B)

$362$

From the given series we can write as

$\Rightarrow {11}^2+1=122\Rightarrow {13}^2+1=170\Rightarrow {15}^2+1=226\Rightarrow {17}^2+1=290\Rightarrow {19}^2+1=362$

So option $B$ is correct.
