Answer 2

Answer:

Step-by-step explanation:

Average formulae = sum of all numbers / 2

Average of first fifteen even numbers = 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 +                              

                                                                  20 + 22 +24 +26 + 28 + 30 / 2

                                                               = 230 / 2

                                                               = 115

Therefore, the average of first 15 even numbers if 115.
