1/2, 1/4.

Answer = 21 The next number is the previous 2 numbers added together
This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1
The next four number in the sequence are... 4,5,5 & 6
10,11,13,14,15,17
21 - 34 - 55 - 89... Simply add the 2 previous numbers together to get the next in the series. 1+1=2 1+2=3 2+3=5
It is: 128 by doubling the numbers each time
Nt - ninth, tenth
The Fibonacci numbers is a series of numbers that are found in nature and other things. The series goes 0,1,1,2,3,5,8,13,21 and so on. You just add the last two numbers in the series. 0+1=1, 1+1=2, 2+1=3, and so on.

The series appears to be alternating between adding and subtracting numbers. The pattern seems to be adding 1, then subtracting 2, then adding 3, and finally subtracting 4. Following this pattern, the next number in the series would be 1 (subtracting 4 from -1).
