This is an arithmetic sequence which starts at 14, a = 14, and with a common difference of -1, d = -1. We can use the nth term formula
an = a + (n - 1)d
to get an = 14 + (n - 1)(-1) = 14 - n + 1 = 15 - n.
The nth term is (2n - 12).
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.
nth term= 6 + (n-1) (2)
The nth term is n2 + 4n.
The nth term of the sequence is expressed by the formula 8n - 4.
The nth term is (2n - 12).
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.
2n - 12
It is: 2n+4
nth term= 6 + (n-1) (2)
T(n) = 12 - n2
The nth term is equal to 4n.
It is: nth term = 7n-9
If you mean: 6 12 18 24 then the nth term is 6n
The nth term is n2 + 4n.
The nth term of that series is (24 - 6n).
If you meant: 2 12 22 32 then the nth term = 10n-8
