Question

Find the missing number:

$912,303,102,33,?$

• A. $12$
• B. $10$
• C. $8$
• D. $6$

Answer 1

The correct option is A $12$

Given series is $912,303,102,33,?$

Now,$303\times 3+3=912;$

$102\times 3-3=303;$

$33\times 3+3=102;$

Let the missing number be $y$,

Clearly,$y\times 3-3=33$

or, $3y=36$

or, $y=12$

Hence, option (A) is the correct answer.
