1x4=4
4/4=1
Hopefully this is right and helped :)
I put this into good old Desmos since I couldn't figure it out by hand. So here is what I got.
Answer:
20 or 18

Answer:
The sequence is geometric.
Step-by-step explanation:
If the sequence is arithmetic common difference will be same, if the sequence is arithmetic common ratio will be same.
Here the sequence is 4, 40, 400, 4000, …
Difference between terms
40 -4 = 36
400 - 40 = 360
They are not same , so the sequence is not arithmetic.
Ratio between terms
40/4 = 10
400/40 = 10
4000/400 = 10
They are same , so the sequence is geometric.
Now we need to find recursive formula for the sequence.
Recursive formula for GP
