Answer:

Step-by-step explanation:
The explicit formula for a geometric sequence with first term a1 and common ratio r is ...

In this problem, you are given a1=625 and r=0.2. Filling in those values gives the explicit formula ...

You can either evaluate this function for values of n = 1 through 5, or you can multiply each term by the common ratio to get the next.
a1 = 625
a2 = 625·0.2 = 125
a3 = 125·0.2 = 25
a4 = 25·0.2 = 5
a5 = 5·0.2 = 1
To solve this system, let y = x^2 - 4 = -4. Then y = x^2. This is true for all x. There is no single numerical solution. y = x^2 is a function with infinitely many inputs/outputs.
The number on the right is always greater than the number on the leftEx:14 is greater than 8 because 14 is to the right of 8 on the number line.
