###Human: Tony has two fish. Every year, his parents buy him two more, but one of them dies. How many fish will he have in five years?, ### Assistant: Each year Tony has one more fish than before because 2 - 1 = 1
In five years, he will have 5 more fish because 5 x 1 = 5
In five years he will have 7 fish because 2 + 5 = 7 
 So the answer is :  7
