The sequence of differences between consecutive numbers is 9, 1, -20, 9, 1. If this continues then the next difference is -20 and therefore the seventh number is -5. (15 - 20).
Ten.
The answer is 35.
-5
The next number after 15 will be 3. You are sequentially adding 9, adding 1, and dividing by 5.
3
35
You could go for add 9, add 1 divide by 5 or you could have the polynomial (-30x5 + 513x4 - 3232x3 + 9171x2 - 11438x + 5376)/24 and according to that, the next number is -266
21
No. The pattern is: +9, +1, -20, +9, +1, -20... So the next five numbers are: -5, 4, 5, -15, -6.

25-1=24 24-2=22 22-3=19 19-4=15 15-5=10 The next number in the series is 10.
