Balls deep
The nth term is 3n+7 and so the next number will be 22
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.
6n+10
3n+7
It is: nth term = 29-7n

The nth term is -7n+29 and so the next term will be -6
6n+10
1,7,13,19
It is: -6n+22
If you meant: 2 12 22 32 then the nth term = 10n-8
3n+7
The nth term is 5n-3 and so the next term will be 22
t(n) = 29 - 7n where n = 1, 2, 3, ...
