working with bases means to change the numbering system that you currently use. For base six, it goes 1,2,3,4,5,10,11,12,13,14,15,20. Looking at the sequence we see that "20" in this case is 12 of base ten..the numbering system we use. So "15" is 11, "24" is 16, and "31" is 19. You can work it from there.

The pattern is: +11, +15, +19, +23, +27 (4n+7) So, the next number would be: (4*6 + 7) = 24 + 7 = +31 Therefore, the answer is: 105 + 31 = 136
15/24 or 5/8
OK, so-3y + 15 - y = 39-3y + 15 - 15 - y = 39 - 15-3y -y = 24-4y = 24-y = 6y= -6.Hope this helps!
