Answer:
2*30 10*6 1*60 20*3
Step-by-step explanation:
Find 2 numbers that multiplied have a result of 60
5p = 80b
3(5p) = (80b)3
15p = 240b

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
