The answer to your question is:

first test = 72

second test = 88

third test = 89

Step-by-step explanation:

Data

First test = 72 points

Second test = x

Third test = x + 1

Average of the three test = 83

Process

       (First test  + Second test  + Third test) / 3  = 83

       ( 72 + x + x +1 ) / 3 = 83

        73 + 2x = 3(83)

        73 + 2x = 249

        2x = 249 - 73

        2x = 176

        x = 176 / 2 = 88   second test

        third test = x + 1 = 88 + 1  = 89
