-14
The sequence is t(n) = (-12n5 + 215n4 - 1430n3 + 4285n2 - 5458n + 2520)/120
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
The next number is 4, followed by -2
8
243
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 sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
The next number is 4, followed by -2
8
8 -1 then +3
4
1+1=2 : 1+2=3 : 2+3=5 : 3+5=8Therefore the next number is 8
For an integral sequence the next number is 6 (add 5 subtract 7 pattern).
243
If the last number is 1/3 (it should be), the next number is 5 and 1/3
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
64. It's the sequence f(n) = n^3
