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 ].

The 'n'th term is [ 13 + 5n ].
It is: 5n+3 and so the next term is 28
The 'n'th term is [ 13 + 5n ].
The next term is 45 because the numbers are increasing by increments of 3 5 7 9 and then 11
1,7,13,19
It is: 25-7n
Un = 25 - 7n
18,23,28,33,... #1 is 18 #2 is 23 A difference of '5' Hence we can write '5n + x = 18 Where 'n' equals '1' Hence 5(1) + x = 18 5 + x = 18 Hence x = 18 - 5 = 13 So nth term is 5n + 13 NB Verification; does it work for the 4th term 5(4)+ 13 = 20 + 13 = 33 Which is true from above list.
