Here are the first five terms of an arithmetic sequence.

26 19 12 5 -2

Find an expression, in terms of n, for the nth term of this sequence.

(I know part of it is -7n but I'm not sure what the rest would be)

Answer:

the answer is -7n+ 33

Explanation:

i usually just add the constant difference to the first term to create the last value . it sometimes doesnt work but does most times
