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.
next in the sequence: 10,20,30,20
10
10
10 is one possibility.
The next number in the series 1 2 4 8 10 20 22 is
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.
what number is next in the sequence: 10,20,30,20,(? 30
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
20. Next is 18
6
40 5 10 20 40 80 160.......double the number each time.
22
