Well, you only listed three pieces so far.  But I can already see a 
pattern emerging from those three.
Of course, the next piece might return to 1-1/2 inches.  I mean, 
the pattern can't just keep on going and increasing forever or 
Cody would eventually wind up with pieces that are a mile long.  
It must eventually return to 1-1/2 inches and start over from there.
From the first piece to the second one, and from the second one
to the third one, the increase is  5/16 inch both times.  So if the
pattern is more than three pieces long before it starts over from 
1-1/2, then the next piece is
             (2-1/8 + 5/16) = (2-2/16 + 5/16)  =  2-7/16 inches .
        
             
        
        
        
There are 1,000 grams in a kilogram. 
Each gram of water has a volume of 1 milliliter (the question said millimeter but that measures length and I think it was meant to say milliliter). 
Since there are 1,000 grams with a volume of 1 millimeter each, the volume is 1,000 milliliters, which is equal to 1 liter. 
Hope this helps!
