21. Add the last 2 numbers to get the next.
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.
16 is the next squared number.
The next number in the sequence is... 64
16
21. Add the last 2 numbers to get the next.
21. This is the Fibonacci series.
The numbers are increasing by 1,4,9,16,25,36.... which are square numbers so the next increase is 49. Making the next number in the sequence 141
34. Each number is the sum of the two preceding numbers. This is called the Fibonacci Sequence.
1, you are taking away 5, 4, 3, 2, 1
If x(n) represents the nth number is the sequence x(n+1)=x(n)*(x(n)+1) So the next number in the sequence is 1086*(1086+1)=3263442
3024 1 x9 99 x8 7272 x7 504504 x6 3024
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
The difference between each number and the next number is a power of 3: 1, 3, 9, 27. So to get the next number, just add the next power of 3 (81).
The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.
