Question

Complete pattern - 0,3,3,9,12,21,__ ?

A: 33
B:30
C:42
D:24

Answer 1

Answer:

A: 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,

$12 + 21 = 33$

33 must be the answer.

Answer 2

The required "option A) 33" is correct.

Step-by-step explanation:

The given series:

0, 3, 3, 9 ,12, 21, ____ ?

To find, the missing number (?) = ?

The pattern follow:

The addition of previous two numbers.

3 = 0 + 3 = 3

9 = 3 + 6 = 9

12 = 9 + 3 = 12

21 = 12 + 9 = 21

Similarly,

? = 21 + 12 = 33

∴ The missing number (?) = 33

Thus, the required "option A) 33" is correct.
