Given ANY number whatsoever, it is easy to find a polynomial of order 5 that will generate the above five numbers and your sixth as the first six. So the simplest answer to the question is what would you like it to be - and I can find you the rule that works for it.
However, the simplest polynomial of order 4 that fits the above numbers is
Un = (103n4 - 1242n3 + 5201n2 - 8670n + 4680)/24 for n = 1, 2, 3, ...
and accordingly, the next number is 213.
The answer is: 12.
10 ten
32 The rule is to add 3n, where n is the number of the number in the series. (add 3, 6, 9, 12).

The next number in the series 1 2 4 8 10 20 22 is

10.

There is a "Fibonacci" like series is that each digit is the sum of the preceding two numbers: 4 + 8 = 12 8 + 12 = 20 So the series continues: 12 + 20 = 32 20 + 32 = 52 32 + 52 = 84 52 + 84 = 136 and so on. ----------------------------------------------------------------------------- What number do you want to be next? Give me a number and I'll give you a polynomial so that putting in 1, 2, 3, 4 gives the values 4, 8, 12, 20 and putting in 5 gives the number you want.
The next number in the series 1 2 4 8 10 20 22 is
Hi
The next number is 20.
