The answer is 8 because 1+1=2, 1+2=3, 2+3=5,and 3+5=8.
If you fit the following cubic t(n) = (-n3 + 9n2 - 20n + 18)/3 where n = 1, 2, 3, ... then the next number is t(6) = 1
There does not appear to be a missing number. The sequence is n2 + 1. 12 + 1 = 2 : 22 + 1 = 5 : 52 + 1 = 26 : 262 + 1 = 677. The next number in the sequence is 6772 + 1 = 458330.
1 + 1 = 2 2 * 2 = 4 4 - 1 = 3 3 + 3 = 6 6 + 2 = 8 8 - 1 = 7 so you just repeat that .. meaning that the next number is 15
15
The next number is 4, followed by -2
The next whole number after 1 is 2
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
let look at it and figure it out.. 1111 means the following first number on the right is the number of 2^0s which is 1 next number is the number of 2^1 powers or 2's next is the number of 2^2 =4s next is the number of 2^3=8 s So we have 1+2+4+8=15
16 is the next number. All you do is sequentially add the next odd number. Therfore after 16 the next number would be 25... the next 36... the next 49... the next 54...
The third number is 2 -- the first number is 1, second is 1, next is 1+1=2, then 1+2=3, 2+5=5 etc.
You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.
If you mean: 1, 2, 4, 8 and 16 then the next number is 32
