<h3>
is the recursive formula of the geometric sequence</h3>
<em><u>Solution:</u></em>
<em><u>Given geometric sequence is:</u></em>
-0.6, 3 , -15, 75
We have to frame the recursive formula
Find the common ratio
Thus common ratio is -5
<em><u>The nth term of geometric sequence is given as:</u></em>
Where,
n is the nth term
a is the first term of sequence
r is common ratio
From sequence,
a = -0.6
r = -5
Therefore,
Where, n = 1 , 2 , 3 , 4 , .....
Thus the recursive formula is found
