15 would be the next number.
The sequence is x multiplied by two plus two minus one.
1 2 4 3 6 8 7 14 16 15 30 32 31 62 64 63
Each process or addition/multiplication is shown in each number.
The pattern is double, +2, -1.
1 2 4 3 6 8 7 14 16 15 30 32 31 62 64 63 126 128 127 254 256 512 514 513 1026 1028 1027 2054 2056 2055....
This sequence is created by alternating differences. The difference pattern is 4, 3, 5, 2, and 6. The next difference is 1, so the next number is 13.Ê
The next numbers in the sequence are 15 30 32.
1 times 2= 2
2 plus 2 = 4
4 minus 1 = 3
3 times 2 = 6
6 plus 2 = 8
8 minus 1 = 7 etc.
Not sure what completes the sequence. The answer below simply continues it which is NOT the same thing.
15, 30, 32
None of them. I make it 15.
U1 = 1
U2 = U1 * 2
U3 = U2 + 2
U4 = U3 - 1
Repeat the last three.
The number which best completes the sequence below is:2 9 5 13 10 19 17?
The number which best completes the sequence below is: 2 9 5 13 10 19 17 ?
The number which best completes the sequence below is:1 1 3 2 4 6 5 25 ?
We can't answer this accurately without knowing the sequence.
7
77040
== ==
27. But that continues the sequence, it does not complete it.
27
25
It is: 10-3 = 7
The number which best completes the sequence below is 20 5 30 6 42 7
