times 8, divided by 4
16
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
Each number is twice the previous number.
15,30,32,31,62,64,63..... (*2,+2,-1)
The 40th number in the sequence will be 40 x 4, or 160.Reasoning:Because the sequence is multiples of 4.The 1st number in the sequence is 1 x 4, or 4.The 2nd number in the sequence is 2 x 4, or 8...The 4th number in the sequence is 4 x 4, or 16...The 17th number in the sequence is 17 x 4, or 68
16
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.
The next number in the sequence is 15 - the sequence goes x2, +2, -1
16
consecutive multiplying by 2.
The next number in the sequence 2, 4, 16, 64 is 256.
If you mean: 1, 2, 4, 8 and 16 then the next number is 32
x 2 + 2 - 1 is the repeating sequence 1 x 2 = 2 2 + 2 = 4 4 - 1 = 3 3 x 2 = 6 6 + 2 = 8 8 - 1 = 7 7 x 2 = 14 14 + 2 = 16 16 - 1 = 15 the next number is 15
c) 17
The sequence doubles for the first one, then adds two for the next number, then subtracts one for the third, then repeats. So the next number is 15.15.It's a three step operation : x 2, + 2, -1,The step after 16 is -1 which gives 15.
3 It falls between 2 and 4. However, the sequence is incorrect. I believe you mean to do the Fibonacci sequence which is 1,1,2,3,5,8,13.The next number in the series is 16.The numbers are increasing by consecutive integers (+1, +2, +3, +4, +5)
