1.5 but you can’t get half a person
        
             
        
        
        
Let n be the total number of puffs. Now we can write:

Adding the fractional value of n, we get:

Simplifying and rearranging gives us:

Therefore we can simplify to get:

and finally

The fraction of the puff that are tuna is found from:
 
 
        
        
        
The answer would be (2,3).
Try sketching it out, it helps :) 
        
                    
             
        
        
        
The next step in the series will be Option B 
<h3>What is a Series ?</h3>
A series is the sequence of object in pattern.
From the given figure it can be seen that the red and blue colour semicircle are shifting alternately , and the number series is increasing by 1 
Therefore the next step is red on the right side , blue on the left side and no. 4 written on blue 
Therefore Option B is the right answer.
