The 10th term of the geometric sequence as described in the task content is; 5/2.
It follows from the task content that the 10th term of the sequence is to be determined.
On this note, since the 10th term differs from the 9th term by a factor of r, common ratio.
Hence; a(10) = a(9) × r
= -5 × (-1/2)
a(10) = 5/2.
Ultimately, the 10th term is; 5/2.
