The next term is 91. The sequence differences are: 875 - 874 = 1 = 13 874 - 866 = 8 = 23 866 - 839 = 27 = 33 839 - 775 = 64 = 43 775 - 650 = 125 = 53 650 - 434 = 216 = 63 The next difference is 73 (= 343) which is subtracted from 434 to get the next term: 434 - 343 = 91 The sequence is defined as: U1 = 875 Un+1 = Un - n3 for n > 1
1 8 27 64 125 216 343
The next one is 125.
81
The sequence is generated using cubes, or n^3. The next number in the sequence will be 4^3, or 256.
If the first two numbers are 0, 1 or -1 (not both zero) then you get an alternating Fibonacci sequence.
125 (the sequence is successive numbers cubed)

Your sequence seems to be a cubed sequence, but you are missing 64 between 27 and 125.13 = 123 = 833 = 2743 = 6453 = 12563 = 216So, next would be 73, which equals 343.
