Question:
Find the $5$th term of the given geometric sequence, where $a_n$ denotes the $n$th term, $q$ is common ratio, and $s_n$ is the sum of the first $n$ terms of the sequence.
Question Row 1:
$a_7=10,\ q=\frac12$
Answer Row 1:
$\frac54$, $\frac52$, $20$, *$40$, $80$
Question Row 2:
$s_3=30,\ q=-\frac12$
Answer Row 2:
$-20$, $-\frac52$, *$\frac52$, $10$, $40$
Question Row 3:
