The next number is 39.
The position to value rule is:
Un = (7n4 - 89n3 + 392n2 - 694n + 438)/6 for n = 1, 2, 3, ...
The next four number in the sequence are... 4,5,5 & 6
Consecutive terms in the sequence are being divided by -2. Therefore, -1 / -2 = 1/2 or 0.5.
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.
64
6
To get the next number in the sequence, you simply multiply by 26*2=1212*2=2424*2=4848*2=96
The next four number in the sequence are... 4,5,5 & 6
The next number in the sequence is 27.
Consecutive terms in the sequence are being divided by -2. Therefore, -1 / -2 = 1/2 or 0.5.
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.
You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.
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.
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
The next number is 4, followed by -2
The next number in the sequence would be 23. The sequence consists of prime numbers.
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
The sequence is decreasing by a factor of 5 each time, so the next number would be -2.
