This looks like a (subtract 5; add 2) series, so the next numbers are: 2, 4, -1, 1
The next number in the series 1 2 4 8 10 20 22 is
The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.
This series is of the function f(x) = x2+1, starting with x=0.The next number in the series is 26. The number after that is 37.
