Question

$3,20,18,14:5,14,9,7::6,15,12,10:?$

• A. $12,18,17,11$
• B. $4,13,11,15$
• C. $6,7,8,9$
• D. $12,8,15,4$

Answer 1

The correct option is B $4,13,11,15$

Each group of numbers form a rhombus shape separately when the numbers of that group being joined by a line.

Also, the next group starts with the number which is $2^{nd}$ from the first number of previous group.

So, the next group also form a rhombus shape and starts with $4$.

Thus, the missing group of numbers will be $4,13,11,15$.

Hence, option B is correct.
