$6$ $:$ $42$ $:$ $:$ $7$ $:$ $?$

• A. $40$
• B. $56$
• C. $48$
• D. $52$

Answer 1

The correct option is B $56$

We can see the following relation:

$6(6+1)=6\times 7=42$ and $7(7+1)=7\times 8=56$

So, $6$ and $42$ are related the same way $7$ and $56$ are related.

Therefore, the correct answer is $56$.
