1+1=2 : 1+2=3 : 2+3=5 : 3+5=8
Therefore the next number is 8
The next number is 4, followed by -2
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.
34
4
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
If you mean: 1, 2, 4, 8 and 16 then the next number is 32
18
The sequence indicates that one number is added to the previous number to find the value of the next number. Example 1 (+0) - 1 (+1) - 2 (+1) - 3 (+2) - 5 (+3) - 8 (+5) - 13. The next number in the sequence would be 21 (13 + 8).
16
21
8 -1 then +3
8
