Question

In a garden, the number of flower plants follows the rule "add 3" and the non-flower plants follow the rule of "multiple 4".


The missing number is .

• A. 10
• B. 12
• C. 13
• D. 15

Answer 1

The correct option is B 12

It is given that number of flowering plants follow the pattern "add 3".

Let us represent the number of the flowering plants on a number line.


Now, from the number line, we can see that the number of flowering plants increases by 3 for every step jumped.
0 + 3 = 3
3 + 3 = 6
6 + 3 = 9

So, the next number when flowering plant will appear will be 9 + 3 = 12.

From the number line also, we can see the following:


∴ The number of flowering plant in the next step will be 12.
