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
