Question

Observe the given pattern and answer the following question.

How many green dots will be present in the next in the pattern?

• A. $17$
• B. $19$
• C. $13$
• D. $15$

Answer 1

The correct option is A $17$


We can observe that there are $1,5,9,$ and $13$ green dots in the first, second, third, and the fourth terms of the pattern, respectively.

$1+4=5$
$5+4=9$
$9+4=13$
The number of green dots in each consecutive term is found by adding $4$ green dots to the previous term.

Number of green dots in the next term $=13+4=17$
