The nth term is (2n - 12).
It is: nth term = -4n+14
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.
100,000,000,000
The nth term is 3n+7 and so the next number will be 22
The nth term is: 3n+1 and so the next number will be 16
100.

The nth term in this arithmetic sequence is an=26+(n-1)(-8).
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
It is: 26-8n
It is: 3n+1
