Hey there!
A geometric sequence is where we use multiplication or division to get to the next term.
In this case, we use multiplication (we multiply every term by 3)
So we have
-1, -3, -9, -27, -81, -243...
Steps:
- Since we multiply every term by 3, we multiply -9 times 3. then we multiply the product of 9 & 3 times 3, and so on...
Hope everything is clear.
Let me know if you have any questions; if oyu do, kindly comment below my answer.
