Answer:
-1220703125 is the 14th term of the geometric sequence.
Explanation:
The following geometric sequence has the common ratio of -5 as -5/1 = -5 and 25/-5 = -5.
Then apply in the geometric sequence formula which is:

where
represents the nth term,
is the 1st term and
is the common ratio. Substitute in the known values:

Since we want to find the 14th term of the sequence, substitute n = 14:
