Answer:
The 4th term of the geometric sequence is 8x².
Step-by-step explanation:
First term: 5x²
Common ratio: x²
So the pattern will be:
5x² + x² = 6x² ( 2nd term )
6x² + x² = 7x² ( 3rd term )
7x² + x² = 8x² ( 4th term )
8x² + x² = 9x² ( 5th term )
So the 4th term of the geometric sequence whose first term is 5x² and the common ratio is x² is 8x².
