You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.

This sequence is the squaring of the numbers 1, 3, 5, and 7. The next number is 9^2 = 81.

If you mean: 1 4 9 16 25 then it is 36

It is: 6 squared = 36

13, because if you add the last number to the current number you get the next number

I'm fairly sure you meant the "4" to be a "3" in this sequence. There is no "next number" in the sequence given, since there is no rule that encompasses the entire sequence. And to be fair, in number sequences, any number can still logically be "next". If it's not the number that you expect, it is still a number sequence. It is just not a predicable one.

These are Fibannoci's numbers. Therefore, the 7th number is 21.

You cant solve the next term (next number) in this sequence. You need more terms, because this is either a "quadratic sequence", or a "linear and quadratic sequence", and you need more terms than this to solve a "linear and quadratic sequence" and for this particular "quadratic sequence" you would need more terms to solve nth term, which would solve what the next number is. If this is homework, check with your teacher if he wrote the wrong sum.

The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.

The next number is -20. The sequence appears to be the Fibonacci sequence but it is not. One possibility is that it is the sequence generated by the polynomial: t(n) = (-17n6 + 369n5 - 3095n4 + 12795n3 - 27128n2 + 27876n - 10080)/720 for n = 1, 2, 3, ...

25 is the next number that appears in that sequence.
