<u>Answer:</u>
The 4th term of the geometric sequence with = 5 and ratio (multiplier) = -3 is -135
<u>Solution:</u>
Given that, first term a of a G.P = 5 and common ratio ( r ) = -3 for an geometric progression.
We have to find the 4th term of the above given geometric progression
We know that, nth term of an G.P is given by
So, now, 4th term is
hence, the 4th term of the given G.P is -135
Using finite difference, the answer is cubic. Apologies if I’m wrong
