Answer:
<h2>Step-by-step explanation:
Since the sequence above is a geometric sequence
For an nth term in a geometric sequence
<h3>where
a is the first term
r is the common ratio
n is the nth term
To find the common ratio divide the previous term by the next term
That's
<h3>So the common ratio / r = 7
the first term is - 1
Substitute the values into the above formula
<h3>We have the final answer as
<h3>Hope this helps you
