Answer
Explanation:
Step1: Analyze step - 1
In step 1, there are 4 dots.
Step2: Analyze step - 2
In step 2, there are 8 dots. We can observe that the number of dots in step 2 is (4\times2).
Step3: Analyze step - 3
In step 3, there are 12 dots. The number of dots in step 3 is (4\times3).
Step4: Find the general rule
The number of dots in the (n)th step is given by the formula (4n).
Step5: Calculate for the 5th step
When (n = 5), we substitute (n) into the formula (4n). So the number of dots is (4\times5=20).
Answer:
20
