What comes next 3 8 63 3968?

The sequence appears to follow a pattern based on multiplying the previous number by an increasing power of its position in the sequence. Specifically, 3 × 2 = 6 (then add 2 to get 8), 8 × 7 + 7 = 63, and 63 × 63 + 63 = 3968. Continuing this pattern, the next number would be 3968 × 3968 + 3968, resulting in a very large number. The exact calculation will depend on the specific formula you use, but the next term is derived from the same multiplication and addition pattern.


What is the next number in sequence 6122448?

To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96


What number is next in this sequence 2 9 5 13 10 19 17?

The next number in the sequence is 27.


What is the next number in the sequence of 13.18.16.21 and 19?

The sequence appears to be decreasing by 2, then increasing by 5, and then decreasing by 2 again. Following this pattern, after 19, the next number would follow the same decrease of 2. Therefore, the next number in the sequence is 17.

What number comes next-1 2 -4 8 -16 32?

You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.


What is the next number of -1 0 7 26 63?

The sequence appears to follow the pattern of ( n^3 - 1 ) for ( n = 1, 2, 3, 4, 5 ). Specifically, the numbers correspond to ( 1^3 - 1 = 0 ), ( 2^3 - 1 = 7 ), ( 3^3 - 1 = 26 ), and ( 4^3 - 1 = 63 ). Therefore, the next number would be ( 5^3 - 1 = 124 ). Thus, the next number in the sequence is 124.


6 21 40 63 90 121 what is the rule for this sequence?

(1) Take the difference of the two previous numbers in sequence (2) Add 4 to this difference. (3) Take the number from step #2 and add it to the previous number in the sequence. For example, to find the next number in the sequence: (1) 121 - 90 = 31 (2) 31 + 4 = 35 (3) 121 + 35 = 156


What is the next number sequence 49 64 81 100?

The given number sequence is a series of perfect squares: 7^2, 8^2, 9^2, 10^2. Therefore, the next number in the sequence would be 11^2, which is 121.


What is the next number in the sequence 3 4.5 6.75 10.125?

The sequence is taking half of the number and adding it to that number, 3/2 = 1.5, 3 + 1.5 = 4.5, the next number in the sequence is 15.1875


What is the next number in sequence after 1 2 0 3 -1?

The next number is 4, followed by -2


What is the answer to this number sequence 2 4 3 9 8 64 63?

The number sequence appears to be alternating between multiplying by 2 and subtracting 1. Starting with 2, we get 22 = 4, then 4-1 = 3, then 33 = 9, then 9-1 = 8, then 88 = 64, and finally 64-1 = 63. Therefore, the next number in the sequence should be 6363 = 3969.
