1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
16
21
Consecutive terms in the sequence are being divided by -2. Therefore, -1 / -2 = 1/2 or 0.5.
21. Add the last 2 numbers to get the next.
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.
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
4
If you mean: 1, 2, 4, 8 and 16 then the next number is 32
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
18
16
To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96
8 -1 then +3
21
8
