Answer 1

n, n + 3, n + 4, n + 5, n + 6, n + 8, n + 10, n + 12, n + 15
                                   ------
                                      |__ -> n + 6 = 10
                                                 n = 10 - 6
                                                 n = 4

4+4+3+4+4+4+5+4+6+4+8+4+10+4+12+4+15           99          _________
