Answer:

Step-by-step explanation:
General arithmetic sequence formula: 
where
= first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: 
We have
and d = -7
So the formula to find the nth term would be
