Question

Complete the following series:

$4,6,12,14,28,30,?$

• A. $32$
• B. $60$
• C. $62$
• D. $64$

Answer 1

The correct option is B $60$

The series can be solved in the following way

$4+2=6$,

$6\times 2=12$,

$12+2=14$,

$14\times 2=28$,

$28+2=30$,

$30\times 2=60$.

Hence $60$ replaces question mark.
