Answer 2

Answer:

33

Step-by-step explanation:

Considering the given pattern,

0,3,3,9,12,21,__

The sum of the two digits leads to the successive digit like:

For example, the first element, 0 adds to second element, 3 gives third element which is 3 as shown below:

$0 + 3 = 3$

Similarly ,

$3 + 9 = 12$

$9 + 12 = 21$

So,

$12 + 21 = 33$

Thus,

33 must be the answer.

33 must be number which should satisfy the series according to it's pattern.
