A Correct answer
Explanation

Previous 2 terms are added to get the next term. Straing from the third term, 5 + 5 = 10                                            10 + 5 = 15                                            10 + 15 = 25                                            15 + 25 = 40                                            25 + 40 = 65                                             40 + 65 = 105 So, 15 and 40 are the missing terms.
