The next number is 4, followed by -2
You add two then take one. 1+2=3, 3-1=2, 2+2=4, 4-1=3. The next number is 5.
2
4.
The next number in the series 1 2 4 8 10 20 22 is
8
The Pattern is 1^2- 2^2- 3^2- 4^2- 5^2 or 1 - 4 - 9 - 16 - 25 The next number in the series is 6^2 or 36
1
If you mean: 1, 2, 4, 8 and 16 then the next number is 32
The next number is 1595. The series is obtained by multiplying the previous number by 4 and then subtracting (n - 1). 1st number = 2 - ( 1 - 1) = 2 2nd number = (4 x 2) - (2 - 1) = 7 3rd number = (4 x 7) - (3 - 1) = 26 4th number = (4 x 26) - (4 - 1) = 101 5th number = (4 x 101) - (5 - 1) = 400 6th number = (4 x 400) - (6 - 1) = 1595
This is a 4 step sequence , starting with the number 1. 1) Double the number 2) Add 2 3) Subtract 1 4) Return to step 1) and repeat. 1 x 2 = 2 ; 2 + 2 = 4 ; 4 - 1 = 3 ; ..........7 x 2 = 14 ; 14 + 2 = 16. Then the next number is generated by Step 3).. 16 - 1 = 15
Correct. For example: 1 + 1 = 2 2 + 1 = 3 3 + 1 = 4
