10

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

10

Seems to be a '+1, +2' sequence, so 12 would be next.

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.

it is 31818 - 8 = 1010 - 4 = 66 - 2 = 44 - 1 = 3

The next number is -21

Since each number is one less than the one before it, the next number would be 8.

How about 10 which is also a factor of 60

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.

The Next NumberThe next number is 25 if you use the following pattern: 5, (the number 10), 15 (the first number +10), (the number 10), and the next number is the third number +10 or 25.or you could think of it this way:5, 10 (+5), 15 (+5), -5 (10)The pattern is +5, +5, -5, so the next number would be 15, the next 20, and the next 15.

Each number is multiplied by negative 2 to get the next number. 5 x -2 = -10 -10 x -2 = 20 20 x -2 = -40 -40x -2 = 80 So the next logical number in the series 5 10 20 -40 would be 80.

90 because 66+24 = 90
