Answer
2n + 8

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.
Un = 5n - 2
The nth term in this arithmetic sequence is an=26+(n-1)(-8).
The 'n'th term is [ 13 + 5n ].
The 'n'th term is [ 13 + 5n ].

It is: 5n+3 and so the next term is 28
1,7,13,19
It is: 25-7n
The next term is 45 because the numbers are increasing by increments of 3 5 7 9 and then 11
It is: 26-8n
Un = 25 - 7n
