Question

Complete the series given below by choosing the missing term from the given alternatives.

$16,33,67,135,?$

• A. $251$
• B. $259$
• C. $271$
• D. $289$

Answer 1

The correct option is C $271$

Multiply each number in the series by 2, and then add '1' to get the next number, like $(16\times 2+1)=33,(33\times 2+1)=67$, and so on.

Applying same logic,

$135\times 2=270+1=271$

option C
