Answer: 0.70
Step-by-step explanation the same as decreased by 30%" would be (1.00 - 0.30)(original cost), or 0.70(original cost)
Geez that is real complicated sorry I’m not sure just go with your gut
The explicit formula for given sequence is: 
Step-by-step explanation:
Given sequence is:
-1,4,-16,64.....
We can see that there is no same difference between consecutive terms so we will find common ratio to see if it is a geometric sequence.
Here

The explicit formula for geometric sequence is:

Putting the values of r and a1

Hence
The explicit formula for given sequence is:
