It is: -6n+22
It is: nth term = -4n+14
The Nth term in the series is [ 2N ] .
The nth term is (2n - 12).
The nth term is 9n-2
If you mean: 2 4 8 16 32 64 it is 2^nth term and so the next number is 128
The sequence has a difference of 10, so the nth term starts with 10n. Then to get to -8 from 10 you need to subtract 18. So the nth term is 10n - 18.
The nth term is 22n and so the next number will be 5*22 = 110

The nth term in this arithmetic sequence is an=26+(n-1)(-8).
The sequence given is -2, 4, -8, 16, which can be observed as alternating signs with each term being a power of 2 multiplied by -1. The nth term can be expressed as ( a_n = -2 \times (-2)^{n-1} ), or equivalently, ( a_n = -2^n ) if you account for the sign change. Thus, the nth term formula is ( a_n = -2^n ).
