Answer:

-58, -38, -18

Step-by-step explanation:

if for the nth term, the value is 20n-78, then for the 1st term, the value will be 20(1)-78

So we just need to use this formula for every term, starting from the 1st, until the value is no longer negative

20(1)-78 = 20-78= -58

20(2)-78 = 40-78= -38

20(3)-78 = 60-78= -18

20(4)-78 = 80-78= 2

so those are the only negative terms

What if the arithmetic sequence is negative?

If the common difference between consecutive terms is positive, we say that the sequence is increasing. On the other hand, when the difference is negative we say that the sequence is decreasing.
